Character screen not showing duplicate items

When I first got Space Engineers, it did work for a little while: sometimes, I'd get a skin that I already had, and it appeared in the in-game character customization menu as a duplicate. I even recycled some. However, for at least a few months now, duplicate skins do not show up in the game anymore. How do I know I got them, then? I get Steam notifications, and in my Steam inventory, I got a bunch of items with a number on them denominating how many I got: more than 1.

Even though I have the duplicate items in my Steam inventory, they do not appear in the game, and I'm not sure if I should risk recycling one while the game thinks I don't have any more.

When loading the character scene from the main menu scene, my duplicate items that are showing in my steam inventory are not appearing in my in game inventory for recycling.

When i open a unknow signal i see the first screen but sometimes the second screen doesnt show.

Also when i go to the steam invetory i can see that i found a armor or tool skin in some cases. But i can not see or recycle the duplicates in the charator menu. It seems that when it is a new skin that i havent owned yet it will show up and i can use it but when it a duplicate is doesnt show up and i can not convert it into tokens.

I have added to photo's one with the inventory of steam where it shows that i have 3 rainbow suites. In the other picture it showes that the game doesnt show 3 rainbow suits. Refreshing doesnt help.

Hope you can help.
