Added a Dropzone to a form and then tried to import the fields in server action. The ‘files’ field doesn’t look right.
Also in some rare cases i get duplicate Variables but can only select one.
This happens
If i delete the variable ALL the GET disapears.
This happens a lot when you create an insert step (possibly update step also, can’t remember), this in turn adds all the fields selected in the db itself automatically. If you have imported your variables from a form and they are named the same there are duplicates created, then when you delete a duplicate it often deletes everything and you get what you have posted in the image above. It has been happening for as long as I can remember, I thought it was a feature… 
I reported that bug several months ago, assumed it was fixed
