CHIRP

https://www.repeaterbook.com/repeaters/details.php?state_id=39&ID=450

the repeater above has an offset of 0.24. If I type that offset into CHIRP, it initially seems to take the offset. However, it does not take that offset. When I save the programming file (IMG), and then re-open the file, the offset is changed to 0.2. If I try to program the radio, CHIRP changes the offset to 0.2. If I try to import a CSV file with the correct 0.24 offset, that is changed to 0.2. CHIRP will not take the 0.24 offset required for this repeater.
