Options setting for Breakout rooms

I have experienced this a couple of times.
I have either ticked the box;

Allow participants to choose room

or 

Breakout rooms close automatically after ___  minutes

prior to opening the rooms then either open the rooms some 5 to 10 minutes after setting the information only to find out the Rooms are not open for the participants to choose or the times reverted to the initial time that was set.

If I remember to recheck the Options prior to opening the rooms I am able to correct the setting before opening the rooms

Is there a way to avoid this from happening

Thank you Stephen
