I set up a field to a number and set it's default value to 0. I then set up a checkbox control and set it to my boolen value list. Everything seems to work fine however when setting up another layout and adding the same field and checkbox and clicking the checkbox I then go back to the table and see that there is a question mark in the field. When I click on the field it has a 0 on one line then a 1 on a second line. I have no idea why this is. Any help would be appreciated.
