Observation Field results not found if name of field includes "#" character

The Field "Tree privet #7has three observations, which can be seen in field Details, but are not appearing on “All observations with this field”.

https://inaturalist.nz/observations?verifiable=any&place_id=any&field:Tree%20privet%20#7

Any ideas what’s wrong?

EDIT - Ah, I think it may be the # character…will test and advise

Yes, that was the problem. Moderator feel free to delete this thread if not helpful to anyone else. I have renamed it in case it is useful info to anyone.
