GroupManager Randomly Demoting People!

So Lately I've been having an error after making Parent/Child stuff in GM.http://gyazo.com/8adfed22a38c8d4c20656e33dd2efb59
^ That is my Parent/Child Mirror, after I've added it, I wanted it to be so if I promoted someone in CreativeDefault, they would become the same rank in Member.

That was not what happened after it was added, players are now starting to randomly get demoted, I add someone for example to Dev rank and then they get demoted to Default for no reason after 30-300 seconds.

Example:
Promotion; http://gyazo.com/7bc2d28eee7ef4fabaab03f17062e9b8
After 25 Seconds; http://gyazo.com/205a323a84aaa7499278332cf84932f7
I'm sure no one is doing this, GM is doing it itself.

Any clues on why this has happened?

 

Hi, i'm Ethan. It would obviously have to deal with Parent and Child. I would delete both and toggle them again. And Google this, Google is always an option, and is friendly too!

Best of luck, Ethan.
