[Plugin: Events Manager] One category shows no events on Events page

Hi,

I have 6 categories in Events Manager. If I Look at the Events Category page I can see the number of events assigned to each category and if I click on that number, it displays the events in the Events page. In this case the category is Music which has 23 events assigned.

However if I am on the Events page viewing all the events and try to filer my events to View only the Music category it says No Events Found.

Any ideas?
