wiebbe' spell editor problem :(

Forsome Reason when i uncheck " is an item ability " or " is a hero ability " and then move to another spell, when i come back it remains checked altho i unchecked it :\. i did try to press the save button but it didnt work

i tried with the new editor too, and it wont save anything
i make some changes ,move on , then when i come back it remains unchanged ?!!
