I've just now had the same experience with the studio icons except it was colour studio icons on my Matrix MQ7 configuration. Come to think of it, this isn't the first time either. It appears to be  the icons are not found so they are either not shown or get hung over with the last icon found.  It seems to happen after cleaning the cache or when the cache expirers (3 days I think). The good news is the problem rectifies itself after Kodi has been up and running continuously for at least 20 minutes sometimes much longer, then the icons begin showing. I don't totally understand why this happens but I have observed high internet usage at that time. It's like it is refreshing the extra info for the whole library before it will work smoothly.
