Past events views/shows in The Events Calender list

Hi i have installd the Litespeed plug-in on my wordpress installation last week but today we noted that someting need to be adjusted in the setting for the site to work proporly.

We have a plug-in callad The eventscalender that handle our events and today we noted that that the list that contains all the events containd two old event from last week. The list should not contain old events.

The first thing i did was to deactivate litespedd plug-in and after that it worked proporly.

After activating the litespeed-plugin the list was now showing correct again.

I have not canged any settting so it is all the default settings. But some setting needs to bee adjusted so this not happens again.

Any recommendations where to start or what to do?
