The groups pagination shows wrong amount of pages.
For example. When You have 19 groups in total and in the backend You set the amount of groups a page to 5. Then You would expect to have 4 pages.
The pagination on the groups page however, shows 7 pages. Page 5,6 and 7 show that there are no groups...
Attached screenshots to clearify. On the second screenshot I put some text to explain the problem a bit more....
