Write CSV automatically enters 'column 1' 'column 2' into table

I have a read range activity, and the output of the read range goes into a write csv activity - however the words ‘column 1’ ‘column 2’ etc keep automatically adding to the empty cells? How do I stop this from happening - I have also tried to delete range afterwards but the range in the datat able does not seem to delete?

Check the different header Settings:

hasHeaders / AddHeaders

include headers settings

in case there are some doubts inspect the data table after read range within the immediate panel
