I am unable to update the PoS configuration.  The system keeps saying "Unable to modify this PoS Configuration because there is an open PoS Session based on it", even though there are no open sessions.  (it says "New session", not "opened by _____" next to the PoS on the dashboard)  I have opened and re-closed, validated and posted on every terminal that has this particular PoS available to it, to the point that it always says "New Session" to make sure none of them were hanging up the system.

I am using Odoo Enterprise
