Steps to reproduce:

1. Create more than 1000 hostgroups
2. Navigate to Data Collection > Host groups
3. Check Pagination.
4.  

Result:
I have around 2000 hostgroups, most of them start with numbers. It does not show all of them. It should have shown 'Zabbix servers' on the last page.

Expected:
It was supposed to increase the number of paginations so I could see all hostgroups.
