export of Excel Parts list from Treehouse File

Hello professionals,

I have a small problem here. When I want to export an Excel parts list from a Treehouse file, I have to deselect all the columns that I don't need on my parts list later. After I have selected and confirmed everything, everything looks fine in the first preview, but then I get the Excel sheet back with all the columns on it, even the ones I deselected.
Is there a solution for this?

Best regards,
Ramzi
