Problem: Forms are being designed to use fields in columns, but on the front-end the fields are in a list and not in columns.
Solution: Forms uses Bootstrap for the columns markup. Make sure that Bootstrap is enabled (at Toolset > Settings). If you cannot use Bootstrap (because of a compatibility issue, for example) then you cannot use columns in forms.
