Error with animmontages from sequences

When I create an AnimMontage from any animation sequence, it has 110,000 frames for some reason. I am using the Third Person Sample, even using the base sequences it does this.

Same here.

SAnimCompositePanel::SortAndUpdateComposite calls UpdateCommonTargetFrameRate. But SAnimMontagePanel::SortAndUpdateMontage doesn’t call the function.
