Subnautica 2 tadpole issue

I have 2 tadpoles one has 4 upgrade modules in it depth, 2 engine efficiency, and strike armor. The other tadpole will only let me put one upgrade module in. When I try to click to move it does nothing, and when I try to drag the arrows around the box where the upgrades go turns red. Has anyone ran into this issue? Could just be game bug but I'm just curious.
