[NC-52090] Firewall rule will not update following certificate expiry

Question

I'm trying to update a WAF rule following a certificate update. However the rule will not accept any changes. Even to disable it.

Steps are :-

Edit rule. The HTTPS Certificate field is empty and below is some text in red saying ;-

Exchange2013-20190210 Certificate has expired or is not yet valid

So I select the new certificate in the drop down list but when trying to save. It just says (in red at the top) "Firewall rule "Exchange" could not be updated"

I've updated many certificates before and never had this problem in pre v18.
