[2020] I cannot equip any mods, am I missing something?!

Im playing the division 2 on Xbox. I have unlocked all the mods in the perks menu with the quarter master, if have also built several mods at the crafting station. None of the mods show up in my inventory! When I select a weapon, there isnt even a button indication for mods in the lower right hand corner. Im level 9 and all the weapons I have equipped have slots for the mods Ive made or unlocked. What am I missing?!
