Looting death box problem

ON PC..

When i'm looting a death box (when my bag is full). I usually try to off load (right click) say an unwanted grenade to make space for a phoenix kit. It normally disappears from my bag and swaps it for the phoenix kit.   

This is not happening for me since the update.

Currently after right clicking the unwanted item it remains visible in my bag. I have to close my bag and reopen it to see that the item has gone. Then i can look in the death box again and take the phoenix kit.

* Just want to know if this is just me and the issue is my side or if others are having the same issue?
