Thank you in advance.

My current environment is ovirt 4.5.2.4-1.el8, running on centos 7.9.

I'm looking for advice on resolving two issues that have just come to light:

Issue #1: When I attempt to create a template from the oVirt GUI, I click the "Make Template" button, enter the name for the new template, then click the "OK" button.  The OK button highlights, but nothing happens.

Issue #2: When I delete a snapshot, after the snapshot is deleted, I receive this error message from the GUI:
