Renaming Buildings from STEX

[pinkfish411 0]

I've noticed that some, but not all, of the custom buildings that I download can't seem to be permanently renamed fraom in the game for some reason.  I can query them, rename them, and save the change, and the change will last for the rest of the time I'm playing that day, but when I exit out of my city and come back to it later, the building names have been reset to their defaults.

Again, it's only a problem with some (about half) of what I download, not everything, and any of the Maxis standard buildings don't seem to be affected.  I've even tried reinstalling the game and the plugins, but that hasn't helped.  Does anybody know why this might be happening, and is there anything that I can do about it?
