Hi, i have this recurring problem for a while now. Some of my parts who use excel table turn to family CAD configuration, and that makes a whole mess said part custom properties. But when i open the same part with the assembly closed the part is back to normal. I don't have 3dexperience enabled and i don't even have the option to turn those family cad parts back to normal. The only solution i found to this is to check every part that is turned to familycad, open them, and then open the assembly. 
Whats is causing it? Is there a way to turn this off? Can i force the family cad parts back to normal without doing all this work?
