Can no longer delete a device even if a user is level 9 (Global Secure Read / Write)

We have a query relating to user level permissions within Observium.

We were previously running Observium v24.4.13510 (stable).

And we had 2 users set to user level 9 (Global Secure Read / Write),  They confirmed that they had been able to delete devices back on that version of Observium.

Since then, the system was updated to v24.6.13582 (stable).  However, even though they have the same user level as before, they now get a "Permissions error.  You have insufficient permissions to view this page."

Can you confirm if this is a bug, or is this now default behaviour whereby only user level 10 (administrators) can delete devices.

Kind Regards
