I misspoke before and should have clarified that this question is a Multiple Choice Grid. Rows are added by Form Ranger and 2 columns (option 1, option 2) remain the same. Column headers in Google Sheets represent the names of the Rows. In the cell, per user selection, is either option 1 or option 2. My guess is that since each Row contains either option 1 or option 2, it is given it's own column in Google Sheet to capture this data.
However, back to the original issue, whenever Form Ranger auto-updates, a whole new set of columns in Google Sheets (representing an entire new set of Rows in the question) is added.
I hope this is more clear. Thanks!
