Events add on Front Page editor

This problem occurs with Front Page editor add on. When activated every time an archive page is to be shown (sidewide) only the first record of that archive is shown.

When I click events on the other hand, and normally the calender was shown, now just the first even of that month is shown in detail.

When I disable the add on, the problem is gone. Please help, because I do want my users to add their own events.
