Default group title is not being applied consistently

So if I am reading this correctly, there is no fast or easy way to correct all these incorrect titles [the groups titles are not being implemented] except to ask the members to remember to go in and change them (they don’t) and we [volunteer staff] have to manually go in and change them one by one by one?

And also, if we want a primary group - we have to set that manually for everyone if we want the group name to to change to the group name title when they get put into the group. Because we have to uncheck the primary group box? So again, we have to go in one by one by one and set the primary group manually for everyone? [If I am reading these two things correctly, this is very burdensome for thousands of users]

Am I mistaken and not understanding the above correctly?
