Filter using GA4 event name is not working

[patriciaoptiply]

Hi,
I have a report to track click buttons using GA4 event names. In GA4 I see event with data

I have 2 tables in Looker using a filter like this:

But it´s not working when I do the same with event 

click_button_request_demo. 

I typed and save event name, but no data is published:

The tracking was set up in GTM. In debug view is being tracked:

Any tip to solve this?
