Why can't I see my query filters?

I am using LeapFrog Works version 2021.2.4. I have created a query filter for my "collar" table based on a selection of "holeid" entries. I have checked the query and it is Ok in terms of syntax. When I try to apply the query filter to the scene view, the new query filter does not show up in the "Query Filter" dropdown list in the properties section of the Shape List. Any advice?
