P: Android app does not allow filtering by 0 stars

Lightroom mobile for android does not allow filtering by 0 stars. If I view a collection and set the filter options to '=' with no stars selected, it shows photos with any number of stars. It should set the filter to photos with 0 stars, as done in the desktop versions of lightroom. Setting the filter to 1 or more stars works as expected, but not 0 stars.
