I have recently upgrade a reasonable number of OJS installations to v3.1.1-4. Everything seemed fine, and after a few weeks, one of the journal managers reported that in 2 instances a strange behavior is being noticed: when editing some roles (all of them under permission level Journal manager) the permissions on it are no longer editable. The checkboxes appears as disabled, as noticeable in the screenshot attached.
I have the backups of the database and files from the previous installations of both journals, despite I did not notice any issue on the upgrade itself, I can run it again with a debug or something you advise to track the issue. I am asking first because maybe you already know what to look for or even a quick solution for it.
Thanks in advance for your assistance
