I found this post while looking for older unanswered posts. Apologies that this slipped through the cracks!
Since the last leopard shark update, this encounter was not associated with a submitterID, and therefore became public, which means that any user can edit information about it except for its (public) owner.
I don’t know whether that was what resolved the issue or whether you managed to resolve this in some other way, but this encounter now clearly has a locationID.
I’m going to mark this issue as resolved, but please let me know if it is not!
Cheers,
Mark
