Menu desynced and the armor stand now shows nothing

[RoboXGamer]

I am inputted the items through hopper and then open the menu and removed one item
then the armor stand shows nothing
this is the menu did not update when the hopper inserted the new item in.

and now if i click on any item in player inventory on screen then this happens, the cross comes on the arrow but somehow the armor stand gets fixed
