use wpematico and post expirator problem

Hello,
I’m trying to use wpematico free version and post expirator. I set to expire after 5 minutes for test but I see in posts page “never expire”.
Instead, if I modify manually a single post “post expirator” it does its job.
could you check if your plugin can work with wpematico?
this is what i see:
