I have a very large form that I created through PowerApps. In the form, there is 1 field called "business line". It is a single choice drop-down field and and one point, the first choice in the list was the default choice that was set. I have since taken the default away and do not want the business line field to default - I have removed the default from the SharePoint list settings.
What is happening is that the completer of the form chooses a business line lower down on the list, they save it, all is good. Sometime over the next couple of days, the business line choice changes to the first one on the list which was the old default. This appears to be happening when someone goes in and edits the form. (There are actually 2 forms - new and edit) As you can imagine, this is causing us problems. What am I missing? Is there something that I need to be changing in PowerApps - is that why this is happening?
