Change base group
You can join as many groups as you like (all of them, if you can), but one group must be designated as "tribal". It should be the group you go to most often. If there are several such groups, decide which teacher you want to communicate with about organizational matters.
Your tribal group should match your tech grade. E.g. if there are groups for green belts in your area and you are a 5th kup, you should not be written in a group that is from a 10th kup. Carefully consider regularly attending training sessions that match your technical level. For STM and STS members, attendance at the core group is closely monitored.
