Double tap to lock, return to the All app list, when unlocking phone, rather than the home page

I have enabled double tap to lock on alphabets.

But when unlocking the phone, it opens only on All apps list, as the alphabets were enable during the double tap it seems.

It's not a intended action, and due to this I need to again click and go back to main page.

Expected result - unlocking should lead to the home page.

Actual result - Unlocking is leading to all apps list.
