Borrowed Licenses not being returned

[ROBinHI]

I seem to be having a constant problem when my network licenses are borrowed and returned early, they do not clear from the license manager. They still show up as used or as (linger). I tried checking the license in/out again with the same computers with no luck and have to actually wait for the day that I had them set to expire or be returned and then they will show up again. This becomes a huge problem when we need those licenses. Does anyone have any suggestions or fixes for this?

Thanks!
