I can't place the medals from the military career into the display case

Hello to all. 

   I followed your suggestion. I've already tried everything that, the person that you recommended me to read their solution. I've tried everything, Nothing works. I've tried putting the items in the household inventory, removing them, nothing works. I've tried to put them in my sim's inventory, but the game states that I don't own the medals, the game's rules won't let me do anything in the living mode. Just so you know? This is not my first time playing the Sims 4 or making requests for answers or looking for solutions to problems that plague this game. I've read numerous replies and solutions. If the solutions worked? I wouldn't be posting my issues. I don't want to complain, I want to enjoy my Sims 4 game. I have better things to do than complain about this game. I just finished searching for an answer to an issue where I can't rotate my lot or house in the build mode on my Xbox Series X. It keeps switching to the tools, instead of rotating the house or lot in the build mode. The only thing that I do know is that there are numerous problems on my Xbox Series X version and my PC version of the Sims 4. The longer I play the worse it gets. Please give me some real answer, and not a run around? Of course I read some of the other replies and actually tried the solutions. Nothing worked, my Xbox Series X and PC version of the Sims 4 is riddled with bugs. Please help?
