editing package filter 'equality type' is impossible
Trying to edit a package filter to change it from 'greater than', 'equal', or 'less than' to another one of those three is nearly impossible.
Changing it from equal to less than or greater than results in an error saying that:
Validation failed: Invalid filter rule specified, 'version' cannot be specified in the same tuple as 'min_version' or 'max_version'
Chaging it from 'less than' to 'greater than' leaves the less than field filled in (may require a page refresh)
