Solved the issue:
I was correct, the LoadLimit is the problem. By the picture you uploaded, you are using Stations 5 and 7 to carry your weapons, which have a 750 kg LoadLimit
But the LoadLimit you were quoting were from Station 5a and 7a, which have a 2000kg LoadLimit. Which I'm using here as you can see.
So, 2 ways to solve this...one, add TLR, EOGR to Stations 5a or 7a, OR increase the LoadLimits on Stations 5 and 7.
Note, this will NOT solve the issue of the sim using the wrong TLR rack, that is a sim code issue. You can solve it with a custom weapondata.ini/dat file, but it would require a LOT of work. I can explain if you are curious.
