Cosmetic Thread Callout (multi-jog) Leader Controls?

Hi, when inserting a cosmetic thread callout, the leader behaves as expected with a plain leader, however, if I add a jog (covert it to a multi-jog leader), the leader no longer attached to the callout note at the top, but shifts to the centre alignment. The options in note properties aren't changed, nor greyed out, and changing it doesn't move the leader attachment. I've tried forcing it to refresh, moving the view/note, closing and reopening SolidWorks, etc.

I can find settings for hole callouts in the document properties (set to attach at top), but not for cosmetic threads.

Is this a bug, or am I missing a setting?

I would like to jog the leader as there are several dimensions/extensions that it needs to cross (removed for clarity below)... and don't get me started on how/why extensions won't break at a leader.
