Deleting resource packs on storage

Hello, I want to know if this is bug can't slide or navigate to the other side to delete installed resource packs on menu→settings→storage→resource packs..

The only thing I can see is clear cache of marketplace, etc. can't scroll down or slide down to navigate to resoucepack and delete some.. using android device.

I could slide or scroll down to other menu, only on storage menu can't see resouce pack or others.

Only stops at multiselect… tab
