Edit this field box disappears when clicking the criteria-box

Dear Zoho-team,
 
When I wish to change the settings of a field and add criteria to it, the box simple disappears when I click the field to start writing in it. This means that I cannot at the moment add any criteria to any fields in my form.
 
It specifically concerns the fields organisation_skole and organisation_ikkeskole in the form "kontaktrapport". Here I only wish to show the items where "organisationstype" == "skole" and "ikke-skole" respectively. Could you please fix this for me? That would help me a lot...
 
Best Wishes,
 
J
