WD renders stuff in its own way some times. What you are showing is a radio button and not a checkbox.
WD is also particular about what objects are on top.
If if you need a radio button and need to hide the 1/0 values maybe try arranging the field so they are up/down rather than left/right and the make it matrix to hide the 1 and 0.
Okey thanks for you input. Where could I choose to show the radio up/down, it seem to show left/right by default? And also I cant hide the 1/0 and not the radio button?
