What happened

The filter kernel was given an operator it does not implement. The condition is compiled to a predicate that admits every row, so the filter has no effect - it does not hide anything, and it does not hide everything.

The fix

Use one of the documented operators. A condition built by hand, or restored from an older saved view, is the usual source.
