Hmmm...intesting question, I am not sure why this.
Hey LP
Suggestion 1: probably you can change your setting i guess, normally in order depends on 3 options #members or alphabet or either the dated forms the groups from your home page ''groups and teams''
Suggestion 2: Quit all the groups just stay remains those 4 groups you in admin 
sounds good? Lol..
the three options are not stored, when you return to the home are always displayed in the order of size
Have the same problem. Would be nice to set it by "hand".
On your home page, groups are displayed alphabetically.
However, to see all your groups, go here:

LP meant wants all the groups he admin could displaying nicely, perfectly on his homepage so he don't need wasted the time for searching, isn't it this is lazy LP? Lol..unfortunately, we all need to searching our groups like Doggy_Style said.
How about my suggestion 2 ? Hehe
It would be cool if we could rearange our home page as we want to see it.
Recently, I joined several groups, a total of 17 now, and the groups that interest me the most are gone from the home. I am admin of 4 groups and all 4 are not displayed in my home. I wonder why you can not select the 10 to display?
