No delete option in list and form

[Alphons]

Hi, i'am working with joomla 3.2.3 and Fabrik 3.2. I don't have een delete option in the list (hover on delete position shows tooltip with "Delete") and form. Enabling the delete button in the form makes the button visable, but pressing it has no effect. Deleting records in the backend works fine. Access rights on list level are all on Public.

i use the template PurityFX based on the Gantry Framework

What could be the problem?
