Using Koha version 3.08.01.002 Returned books are being checked in (with on-screen confirmation), only to be switched back to a checked-out status under the name of the last patron to check out the book. Originally chalked it up to user error, but upon noticing a large number of occurrences, realized that it is, indeed, some kind of glitch. Our in-hour IT team has been unable to pinpoint the problem.
hi, version 3.8 is no longer maintained and any bugs reported won't get fixed. I'd really recommend updating to a more recent version - it might already fix the problem you see.
