Compatibility with YoothemePro dynamic content ?

 Hi Firecoders...
I have just bought Econa, so I'm not awared of all its functionnality.
I have tried the Joomla Core replacement image field, and I can get what I expect, so no problemo on this side.
But with the custom fiels, I can't get it dynamically in content view.
No image printed. Just a blank field with no content...
Do you know if there's any issue between Econa and YTP ?

If I use a HTML field to get Econa (instead of IMAGE field I have tried first), i get this code :

Looks like Econa plugin is not actif in YTPro. Is that possible or I miss something ?
