According to current NaPTAN data, this stop and the one accross the road are in the right place, but are unmarked stops (naptan:BusStopType=CUS). Guidance on the wiki for unmarked stops (at NaPTAN/Tag_mappings#Bus/Coach) recommends adding highway=bus_stop after confirming the stop in person. Presumably if the stop is completely unmarked that would require seeing a bus actually stop there. The highway=bus_stop tag was added to these two stops by you several years ago in changeset/54845595. Do you remember if you did confirm these stops at the time, or if that tag was added mistakenly?
