Product appears twice in activation manager

The activation manager show one of my products as both activated and pending activation. Im not sure how I got into this situation or what will happen when the pending activation expires

Same here. I’ve seen a number of reports like this, it doesn’t seem to cause any problems and can just be ignored. It is however annoying. The text will eventually change to “Expired”.
Another cosmetic annoyance is that trial licenses also seem to hang around forever:
Hopefully this will be cleaned up in a future update of the SAM, but I imagine it’s not a high priority!

Join the club. Many have this issue, but it is pretty minor so not a high priority.
