I can't edit data in a section on a form
You can only edit data in a dynamic grid if the item was entered as an editable item. However, if you added non-editable items to a dynamic grid section on a form using the Select Subject Data button (), the item data is mapped to a source form such as the Adverse Events form. As a result, you can't edit the items in the dynamic grid section. However, if you edit the item data on the source form, it is updated in the dynamic grid.
