Unable to use profile icons

UPDATE: After some more experimenting I discovered that Icons/portraits sometimes won't de-select when enabling another icon/portrait, leading to multiple icons/portraits being active at once & not updating properly. This occurance is somewhat tricky to replicate and seem to have happened to me spontaneously.

The issue is now resolved for me but devs might want to look into it further, hope this information helps anyone else with this problem!

It doesn't work for me either, but it works fine for my girlfriend, i tried selecting different portrait frames and icons but it still doesn't work , it does however show on the curio cabinet

  

I had this bug for years. The profile icon would never show up in a game, neither when hosting a game nor when playing on a public server. Today I've tried some things and found the solution: I had to delete the file "profile" from "Documents\Klei\DoNotStarveTogether\170612567\client_save\". All the character skin settings (and selected vignettes etc.) were gone, but when I now select a profile icon, it shows up in a server. So something was wrong in this file (maybe an old code that caused a conflict after something was changed?). That's something you should have a look into, as I think there are still many players out there who have the same problem.
