Changes in unrelated fields deletes text field when editing form

[ErikKjellman]

I have a form with several fields. One is a description field and another one is a button controlled variable selection. There are four buttons that toggles the value for a datacard (button 1 = southwest, button 2 = northwest and so on). When I use the form in edit mode for existing objects, something weird is happening. If I change the variables using the buttons, the field where the variable is suppose to go is unchanged, but a second field which is populated from said field is updated. Also, the description is deleted, unless I also add a change to the description (any change will do).

My OnSelect in the Gallery view of the form is

Set(varMode;"Edit");; Navigate([@graveskjema_rediger];ScreenTransition.UnCover)

My OnSuccess for the form is 

Set(CurrentSubmittedRecord; graveskjema_rediger_form.LastSubmit);; NewForm(graveskjema_rediger_form)

My OnSelect that submits the form is

If(varMode = "Edit"; SubmitForm(graveskjema_rediger_form);;Navigate(graveskjema_vis); SubmitForm(graveskjema_rediger_form))

I have no idea where to start my debugging on this problem as the app is starting to get more and more complex. Any suggestions?Note ID 2 before editingForm with ID 2 in Edit mode, changed the number 55 to 66 and the button SØ to SVNote ID 2, no change to KvadrantID 2 in edit mode again, description is gone and Valgt rute has been updated to SV

So the solution to my problem was simple; I had the column setting for the description set to add changes to existing text, leading to multiple lines of formatted text, which the powerapps form could not read. 

I also solved the Kvadrant variable issue by moving the variable out of the form and set it as a global variable, with some reset function on the forms on start if in edit mode, to avoid the impression that the button selected was in fact the selected button. Also , I couldn't get my head around how to set the global variable based on the current selected item if in edit mode...
