It's possible that it's due to having multi-TC and the protection ranges overlapping between cabinets. I've seen this on my own server.
In these situations (which can happen) I would recommend destroying all the cabinets. Place the cabinet you want to upgrade first, try upgrading and then place the rest of the cabinets. That or upgrade by hand...
At the end of the day the multi-TC issue is nothing more than a "bug" in the game, since the game itself doesn't allow you to put multiple cabinets in the same build. And this causes that when you open the cabinet and upgrade it, it bugs because it's not able to get the correct build it's assigned to. It's all a bit strange, really.
