I am currently developing a user profile form with a set of 4 checkboxes in a checkboxsetfield. When selecting all 4 the form posts fine and removing the first 2 works fine. For some reason when I have the 3rd and 4th preselected, and decide to remove the 3rd the site does a 302 redirect when I refresh both 3rd and 4th are still selected. When I uncheck the 4th its the same issue. but if I uncheck both it submits fine. I've tried a various number of combinations with the checkboxes but its something too do with the 3rd and 4th checkbox which is performing a 302 redirect on submit. Has anyone else run into this issue before?
