FSX/Prepar3D Douglas C-47 V3.14 Beta Fixes

Im confused. So do i need the earlier 3.12 version for these fixes or can i put it in the latest 3.14 beta package? Are these official updates??

I installed the original and the fixes. The pilot and co-pilot seats are black without texture. Do you know how to fix this problem. Also what is the use of model.C47_2 and model.GAF. In the aircraft.cfg I see sim=Douglas_DC3_v1.5 but the .cfg is Douglas_DC3_v1.4.

I installed the fix as instructed. two different times. I deleted the orig Beta version after installing the fix because after the fix I only had two models of the AC. So I tried again, this time just putting in the individual folders and files but still only ended up with two models of the plane.

So I went back to the Beta without the fixes.
