The tabs are usually carefully ground or filed off as they don't match the recesses in the housing (obviously they might if you happen to have a serviceable 90-year-old Austin set, otherwise the options are rather limited).
But - I'll say it once more for good measure - the tabs are only for alignment during assembly. It's the "nip" of the housing which stops the shells rotating in service.
