It looks like bug. On Profile page groups aren't sorted well. There are two issues about this:
1) They are sorted fixed way from bigger to smaller. It would be much better to shuffle them randomly, as it was in previous version, or let user to choose the way they are sorted.
2) Moreover, even this current list of groups doesn't refreshes well. You need to join or leave group to let them sort correct way. For example, I joined some group consisted of 20 users. Then this group grew up to 10000 users. But it will not take it's higher place in the list on Profile page, until I join or leave another group.
