Initial unmovable Keypoint on Top left

[Rama]

Hi,
I'm not sure if this is expected, but my GUI has a keypoint on the top left, which I can't seem to remove.

I'm not sure if its a problem with my skeleton file. I'm trying to annotate it to the AnimalPose (https://sites.google.com/view/animal-pose/) standard.
Here's the csv i'm using .

name,parent,swap
head,NaN,NaN
eyeL,head,eyeR
eyeR,head,eyeL
earL,head,earR
earR,head,earL
nose,head,NaN
neck,head,NaN
throat,neck,NaN
body,NaN,NaN
withers,body,NaN
tailbase,body,NaN
elbowFR,body,elbowFL
elbowFL,body,elbowFR
elbowBR,body,elbowBL

Sorry, didn't realise this is the expected behaviour, once all the points for the region are annotated, the top left point is removed automatically.
