Tampering with Sinclair lines?

Hi
Firstly, someone has connected this profile (below) to parents, even if there is a curator note specifically saying the parents of this person are not known:
Barbara Sinclair
Decondly, something has Happened elsewhere too, because just 2 days ago Henry Sinclair 1st of Orkney was my greatgrandfather x 18, as he has been for several years, and now all of the sudden he is supposedly only a3rd cousin 2 days later. I happened to take a a snapshot of hisprofile when he was still my greatgrandfather, so there is proof. I descended through Bethoc Sinclair who now is supposedly a fifth cousin: Beatrix (Bethoc) Sinclair, Countess of Douglas
Also on the same line Egidia Douglas used to be my greatgrandmother, but now she too is a cousin all of the sudden.
Egidia Douglas, Countess of Orkney
I hope someone can find out what has happened and who has changed the descending lines of those historical persons. I obviously can’t see the changes made, since I don’t have the tools.
