Now THAT would definitely be the cause of the issue. If Primal and noStrudel are using a field in their kind 0 notes that is not supported by other clients, updating your profile in any of those other clients won't update that field in Primal and noStrudel. They must be keeping the previous kind 0 with that field included in addition to the new kind 0 without it included, until you update your profile from a client that includes ALL of the fields, at which time they only keep that new kind 0.
