"No data" when adding a filter

I have a Looker report with one GA4 data source. I can add graphs to the report that show the data from this source without a problem. However, when I create a filter to get the data for a selected list of URLs, the chart shows "no data".

I can't figure out why.

Chart used: Table

Different ways I have tried to set up the filter:

  • Include - full page URL - regexp contains - blog/blabla/
  • Include - landing page - regexp contains -  blog/blabla/
  • Include - landing page - contains - blog/blabla/
  • Include - full page URL - contains - blog/blabla/
  • Include - full page URL - equal to (=) https://domain.com/blog/blabla/

All of these return "no data".
I have built reports like this before without an issue. I can't figure out why this filter keeps returning "no data".

Any thoughts?
