Existing Image Missing in Return of "list" Action

We have encountered a situation in Glance where an image exists - we can see its UUID in the RBD store (raw image), we can see it via `openstack image show 5a014319-d1b1-456d-a4ed-dd4ce3ff2dac`, and we can reference it in TF files; but we cannot see it in Horizon unless we force its view action by UUID nor in the output of `openstack image list` or `glance list` CLI attempts.
Terraform builds depend on this image, so we dont want to delete it or we'll have to deal with TF modifications - plus that's no fix, just plastering over whatever caused this odd situation.
The image is for a Windows 2019 VM, raw format, with TPM enabled via hw:tpm_verion and hw:tpm_model options in the glance image properties. All other properties are baked-in standard Glance options. Removing the TPM custom options didn't help.
Stack is Wallaby, deployed via kolla-ansible, with Glance backed by Ceph Pacific (juju-deployed & managed).
Created a new image to make sure Glance is properly updating its image list and the new image does show up correctly. There's something about this specific image which "makes it different" enough to break list actions.
