the order of fields in imported pdf file

is there a way to lock the coulmnlayout after i have re arranged them?

if i re import the form afte ri have made some chnages i have to rearrange the colums again.

Also i appear to have a stray duplicate  phantom checkbox column, i cant delete it or find it in my form.

also i get these errors on import, but yet there is no values under these fields.

The checkbox field Gas Certificate contains an export value. FormsCentral will record the checked state, but will not include the export value.

The checkbox field Purchase Milk contains an export value. FormsCentral will record the checked state, but will not include the export value.

The checkbox field Purchase Eggs contains an export value. FormsCentral will record the checked state, but will not include the export value.

The checkbox field Purchase Meat contains an export value. FormsCentral will record the checked state, but will not include the export value.

The checkbox field Purchase Fruit contains an export value. FormsCentral will record the checked state, but will not include the export value.

any ideas? the form is desiged using indesign and then imported.
