How to select a position without zero coordinates

Hi. I put "filter.zero" but now I need to filter old records in the database so that I don't have old records with zero coordinates in the reports. How can I do this?

I would use sql.
First check that this gives the correct rows:

select * from tc_positions where latitude=0

Then I would run:

delete from tc_positions where latitude=0

Yes, that's it, thanks!
