I have an app with several forms in which I have multiple attributes, including a description field (text). When users wish to edit an existing form I have separate forms that are set to edit mode. This works fine if users only wishes to change the description, but whenever they change an attribute it removes the text in that form the next time it is reviewed. In the data list (sharepoint list) both the old and the new description is visible with timestamp , but when exporting to excel the description is left blank.
Gallery view of existing items
Edit form before editing
Edit form of same item after editing attribute and reopening from gallery view
Item was edited from "test" to "humbug" before. Description field is required, so it is not possible to leave it blank.
