usermin search results getting "This message no longer exists"

I have a problem with usermin when I try searching for messages in my inbox, sent items, deleted items. I thought this was working before but I cannot recall if it was anymore. So basically it finds the email’s I’m looking for, but when I click on them it says “This message no longer exists”.

Has anyone encountered this problem before? I did do an update for virtualmin but it was a long enough time ago…

I am using centos7 on cloud
Operating system CentOS Linux 7.5.1804
Usermin Version 1.751
Authentic theme version 19.21
