There are a number of quality filters applied to the event database before they are displayed in mXrap. This does sometimes cause confusion because a particular event is visible in your other software, but not in mXrap.
The most common cause is the location filter but there may be other reasons. Have a look at the “Event quality settings” video. It goes through all the quality filters applied at your site and how to change them.
