Retergeting bug?

Hey guys, I have run into something and I think its a bug.
I am retargetting from an animation blueprint and the additional curve data is not being created correctly.
The image shows 3 screenshots, on the left is the asset I am retargetting from.
The middle image is if I right click on that asset and retarget to my new skeleton, the curves are copied correctly.
The image on the right is if I right click on the APB that contains that animation and I retarget from there. It retargets all the animations associated with the ABP, but about 40% of them have incorrectly named curve data.
Has anyone else seen this?
Is there a work around for it?
