Edit forms ignores certain changes to multiple fields. For example, if a record has two "Web page" values, both "aaa", changing one of them to "a" won't be processed at submissions creation time. This is due to the fact that when the software checks if the new Webpages are the same as the old ones, it checks whether all old values are present among the new ones. It should also check that all new values are present among the old ones.
