DLP delays in matching a rule and Dynamic distribution groups don't work

I have a problem with dynamic groups and DLP Rules. When I use DLP (Compliance Portal) with a dynamic distribution group or a distribution group or simply M365 group, I get an error if I choose the option for OneDrive and Sharepoint locations:
Actions - Document created by member of - (distribution group) and Document created by (any group)
Problem 1:
"Error: DocumentCreatedbyMemberOf Parameter is supported only in None locations. Either remove the parameter or scope policy only to None."
Problem 2:
The rule don't work. If it was working, just stopped and don't match any other document again.
Problem 3:
It can take more than 5 days to match the rule!!!!! How can that be possible!!! It is a high risk in security.
I need answers please.
