My inventory is BUGGED

I cant move anything theres a red box 4th across 3rd one down, On all my characters. When I click on any other box it defaults to the red box item.

Can you show a screenshot?

Im on PS 4 so not sure how to do that. I literally cant play.

The only thing I can remember doing before it got the red box was making the refined blocks.I quit out the application and it is working again.
