Right data preview, but empty data

How to?
#1

Hi,
I have this map. If I debug it visually I'm able to see the sample data of the third column.
If I run "Scrape", at the end the output is empty.

What am I doing wrong?

Thank you

Hi,

The link selector type will not work for the results per page selection, please use element click instead:
