[EpiData-list] Adding/Revising Checks

I have created the qes, rec, and chk files using 3.1. When I use add/revise on the checks menu, make changes, and then save the file, many of the previously defined labels and commands are deleted. My manual states that a check file can be created by using add/revise or the editor. Can edits to the chk file only be made using the editor?

Thanks much,
