Bug trying to organize groups on the new client

I created 1 group called "duo" that have 1 person. Aside from that i have 2 other groups called "general" and "boards" "General" have everyone from my account and "boards" the same way as "duo" have only 1 person.

When i place duo to be on top of all other groups it stays, but when i open general it randomly throw "duo" down. I cant solve it.

Thank you for your attention.
