Thanks for the question, Gary.
Are you using the Raw data explorer (you see the results in a table), or the Custom report builder (you see the results as a graph)? Without knowing which report you’re using and what exactly you’ve entered into the report options, I can’t really say what the problem is, sorry.
If you can paste your BrewwQL filter here, that might shed some light, or if you’re using the Raw data explorer, you can generate a share code to share all the report filters/fields with us.
Cheers.
