Select Multiple From File not exporting as separate columns #5940

When you export data from a project with a select_multiple_from_file question, the said question only exports responses as XML values and all values show up in a single column even when you select Export Select Many Questions As... -> Separate Columns, or Single and Separate Columns. The 'expected behavior' would be to have it export in the same format as a select_multiple question type - with labels by default, and in separate columns.
Steps to reproduce
✅ Create a form with a select_multiple_from_file question
✅ Deploy and enter data
✅ Go to DATA - Downloads
✅ Open Advanced settings and choose Export Select Many Questions as. -> Separate Columns and click export
✅ Download and open the Excel File
❌ See that the select_multiple_from_file question only exports XML values in a single column
