Small bug in UI

[razumv]

I also noticed a small bug, the display of 20\50\100 indexers per page does not work on the site https://frontier.subquery.network/staking/indexers. It would still add a global filter to search by indexer name.

Thanks for the suggestion, [tikcet: 398]

Page display issue is fixed. It now supports 10 & 20 per page.
