Can't change or mount new loadouts for vehicles / Altitude modifier buttons aren't functional

[Shinpacchi]

I tried the mod earlier and it made the operations more convenient then I found 2 main issues as of the moment. I'm not able to change the loadouts of my units or even mount one on fresh unit, Another issue when trying to change altitude for aircraft waypoints, the displayed buttons that change a large value of the altitude doesn't work either. Please fix immediately, I want to continue using this mod and not go play in vanilla
