Ive been trying to set up the level up menu for some time now but. I was finally able to get the menu to display after leveling up, but now I dont know how make it show the passive items, name and description in the container. That in turn makes it impossible to use the buttons to apply passives. For what its worth, the only thing I can think of that might be the issue is the prefabs for the passive items or the passive item scriptable objects.

Its using the gamemanager inventorymanager and playerstats script. It likely has more cause I messed around with it trying to fix the weapon projectile spawning ontop of other stuff. What Im trying to do is have the menu show up to 4 of the passive items of the 2 I created so far as depending on whether its in the inventory already or its current level and be able to use them since I didnt want to add weapons to the level up menu.
