Changing the freeform on a SL360 template

Hi,

I have imported a "Pick One" template from the content library and changed the freeform to "Pick Many".

The slide is set up as "Pick Many" and the trigger says "Pick Many" but when the slide is previewed or exported it only runs as "Pick One".

Am I trying to do something SL360 doesn't allow or have I missed a step some where?
