5 star app but this update has a bug

I love this app n I am using it from 3 years..! But this update has a bug...many times when I search for something in "explore the index" option then nutrition topic opens up...example I look for HIV n in search results I hit on HIV n then nutrition chapter opens up..
This needs to ve fixed.
Thanks
