cck content (text) fields not showing up in destination

Hi there,

I installed migrate and migrate extra (version 1 of both) and I created a content set. So far so good. The problem I face is that when I go to edit this content set, I don't see any (and I got a bunch) of my cck text fields in the "destination field" column. The weird thing is that I see my FileField with no problem. I ensured that "Support for the content module" is checked in the settings. Is there something I forgot to do or are cck text fields simply not supported (I'd be surprised) or is this a bug?

For the record, I'm using Migrate extras 6.x-1.x-dev with Migrate 6.x-1.1

Thank you all for your support
