How to I check in returned books?

How do I check in returned books? I see the transactions here: https://www.librarycat.org/admin/transactions but I don't see a way to check in/out. Neither can I tell how to do it from https://www.librarycat.org/admin/checkinout. Thanks in advance!

>1 DonnaGarel: You just want to scan in the checked-out books that you're marking as returned on the Check in/out page (https://www.librarycat.org/admin/checkinout), and make sure the status is set to "Returned", then click the "Save" button to return those items. If they were checked out to a patron prior to you adding the "Returned" status, they'll get returned under the appropriate patron/s.

Let me know if you have further q's about this!

Today, 11/27/23 i began to check out books following the instructions on the check in/out tab. Book checked out to the patron just fine. In trying to return it, i found that although it is easy to find the book, mark returned and save the return, when i go to the patron, it is not registered as returned by the patron. What am i doing wrong?

Can you tell me some extra details so we can look closer at this?
1. What browser and OS (operating system) are you using (e.g. Google Chrome, version 90 and Windows 7, etc.)? Do you have any browser add-ons or extensions such as an ad or pop-up blocker?
2. What title are you trying to mark as returned? I see one title in your lending history (https://www.librarycat.org/lib/StPiusXCatholic/item/248244266), I just want to make sure it's the same one.
3. How are you trying to mark the title as returned: what are the steps you're taking to return the item? Please include numbered steps for what page you start on (e.g. the Check in/out page, the detail/book page, etc.), what links/buttons you're clicking for each step to mark the item as returned, and what's happening after each step. Please note any error message/s you're seeing, or if nothing appears to be happening, etc.

Thanks in advance for your help, and your patience.
