In that case, maybe using the inclusion would be much better, as it resolves the overlapping categories. Try only icluding the ‘yoga’ category under the Advanced Options panel, and not excluding anything whatsoever. It should force only the ‘yoga’ category.
Then, try a few test searches. If not quite correct, then also try turning off this option. The results should be anything from ‘yoga’ and matching the filter options.
Let me know about the results.
