I'm able to reproduce this bug.
If there is a bin open above a pouch, you cannot drag the contents of the bin to the pouch in some situations.
I was able to brake the bug by first opening the pouch, than opening the bin, than clicking back on the pouch before drag n dropping from the bin into the pouch.
This may be situational on the screen as well, since, if you have 1080p resolution and put 3 bins side by side starting with the first in the top left corner, than put a pouch under each bin, the 3d bin will have this bug/issue while the 2nd bin will not have this bug/issue.
Its a weird one.
