Acrylic shower surrounds w/ framed glass doors

This seems a simple install for both products but.......
The OHWebsite installation shows caulking the bottom rail of a framed glass door to a shower. Here'e the problem, if sealed with silicone inside and out on the horizontal line between the bottom rail and the top of the shower base and the rail has inside weep holes in it, where does the water drain too? I'm getting mildew and black mold outside the frame at the baseboard.
I also question the installation of the acrylic panels installed by my builder. The wall panels overlap the shower base naler on the horizontal portion of the bottom of the panel. There seems to be no seal where the two come together. Yellow mildew is appearing at the joint. Does anyone think this is an install following mfg.'s installation guidelines or just typical and I should maintain the cleaning with a proper mildew remover?
I'm having problems with attaining the name of the door or the shower surround mfg.'s name. To me following their installation instructions would be best and at this point I'm not sure if either product was installed correctly.

All installations of acrylic surrounds that I've had done have been caulked at all joints, including the tub/shower pan. And yes, the nailer lip does go up behind the surround, this is to prevent water wicking under the edge and back into the wall, however, it doesn't prevent the water from getting back there and traveling to the floor, which is likely the cause of the mold problem at the baseboard.

The shower door frame is caulked at least around the inside perimeter, if not the outside too. The weep holes are in the side of the track, which should stand off the edge of the tub by about an 1/8". Any caulking, properly applied, shouldn't affect the ability of the weep hole to drain the bottom track, while sealing it to the surface of the tub/shower. In addition to the track being sealed to the tub/shower surfaces, it is important to seal the corner joint between the bottom rail and the sides, otherwise you'll have leakage here that will find it's way out.

Thanks for the quick response to my question.
Yesterday I got a hold of the factory website for the door and I checked the installation guidelines. It appears that for the door the only portion that is caulked is the vertical rails of the frame. They state not to caulk the bottom rail. It makes sense when you think about it. The weep holes must drain back to the shower. And I remembered that a customer service rep was the one who siliconed the bottom rail after the original installation. The water was in the rail and traveling on a slope to one end of the top of the shower pan. Then the water worked it's way between the end of the rail, top of the pan, and bottom of the panel outside to the wall and base. For now I cleaned and recaulked the outside and removed the interior side to see what happens.
As for the acrlyic surround it may be a good idea to seal it. I will take your advice but need to also check with a manufacturer of a unit that supplies both the panels and the base. The one I did find didn't call for caulk. In fact mine has a larger/wider opening between the two components on the two sides near the door rail. It's distinctivly different from the rest of the joints between the two. It must be an opening for weeping or draining the panels.
