Search returns no results (except chapter:verse)

The search feature of the Al Quran app is not working since last year. If I search for anything on the app, both in English and Arabic, it doesn't bring out any result except I search with Chapter and Verse number. It automatically adds Filter to my searches and I didn't even add any filter. When I click the filter to unselected it, none of the filters is checked but it displays one (1) in parentheses beside the Filter. Jazakummullah khairah.
