Problem with dynamically moving a sprite along a curve

[sysameca]

Hello guys. I am having a scene with a 2d sprite where i am creating dynamically a CatmulRom curve.Everything is just fine except the sprite orientation.So when i start creating the curve from the front side of the sprite where the sprite up vector is, it moves and orients just as it suppose to, but when i start creating the curve from the other side the sprite moves just fine, but comes out flipped in the opposite direction of the curve's tangents.I am moving and rotating on the same principle exposed in SpriteWalkerDistance.I am using as i said a CatmulRom curve with Orientation set to tangents, No CP rotation, Initial Up Vector - Control points.Can you help me understand what is happening?Thank you in advance
