"Something went wrong"

Hi once again! So I was uploading a stock upgrade and I noticed the plugin is not saving my settings of header, and when I load the .csv and I click “Run” I get the “something went wrong” message but I doesn´t seem to be processing anything. The message pops too soon to be a problem in my .csv.
