Successful template check in, but derived objects not updated and template still shows checked out after the check in dialog box indicates success

Template check in succeeds, but template is still marked as checked out, and derived objects are not updated with the change I applied before checking the template in. The only change to the template I am trying to check in is renaming an associated graphic (linked content from the visualization toolbox).

Aveva System Platform version = 2023 R2 SP1 P01

Bullet point troubleshooting measures/ steps taken to try and rectify so far, but were unsuccessful include:
- rebooting the GR node
- restarting the aaGR service on the GR node
- stopping & starting the aaGR service on the GR node
- undeploying & redeploying the entire galaxy
- disassociating the linked content from the object entirely & checking back in, reassociating the linked content & checking back in
