MDTF + The Event Calendar

Hi,
First, i’m sorry for my english…

On my website, i’ve created events with The Event Calendar plugin.
When I’m searching for posts width MDTF, there is no probleme (u can see on my homepage on the right “Rechercher un parcours”.
But when i want to search any event of The Event Calendar with MDTF, results are found but not displayed.
How can I make MDTF displaying events in the results ?

I noted something suprising. When I install and activate the plugin All in One Event Calendar and that I’m logged in my website as a superuser, the MDFT filter displays the events of the plugin The Event Calendar in the resultats. No way I understand this quirk…

Thanks for your help…
