Since it seems I can only replicate this on Android at this moment here's a screenshot of what I get after clicking a stack of 5 wood logs in the hotbar.
This results in having a stack of 5 logs under my cursor and a stack of 5 logs in the hotbar. It looks like I'm duplicating slots but it's actually just out of sync.
I'll investigate
