well triggered spells you need to export the trigger and ability data from the respective editors, however importing in your map will delete anything you have already, so you will need to copy and paste each ability one by one (or make your own) and copy each trigger folder one at a time (or move them all to one folder then copy)
That is done under the hero itself. There are some fields near the top of the Object Editor for the hero called Abilities. There are both Normal and Hero abilities. You can add your ability there depending on what type of ability you have.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
