System Tray notification area oddity

I've looked all over for an answer to this and I can't find it. Am I patient zero? If I have one icon showing in the notification area it appears just fine. If I turn in another icon to show on the notification area the new one shows and the fist one turns into a blank area. If I turn off the first icon the blank area disappears and the remaining icon moves over into its place. Likewise if I turn on all icons the one closest to the New Notifications icon is blank. I've tried resetting the notification area icons but noting changed. I am dazed and confused.

I tried both suggestions and rebooted and I still have the same issue.

I tried the cache rebuild but the issue persists. This is, was, a new PC. It came with Win10 installed. I think this issue has been around since I first fired it up back in August because I thought I set the network icon but wasn't seeing it. It didn't bother me too much but for some reason I just noticed it was happening. Without really paying detailed attention to it over the months I can't say for sure when it started.
