hey I just figured this out, when you unlock the weapon transformations, if you have binded PC keys to the controller with DS4, the 'e" button that I had binded to R1 (ps4) did not work to transform the weapon in the menus, but in game it worked for interacting as intended, so what I did was binded another button (Ps4 share button) to E as well. Now when I go to menus and hit share (e) it transforms the weapon. Not sure why this interaction is doing this, but this works for me. If anything else comes up ill check back
