Help with AnimationNodeBlendTree, turning my timeseek negative when adding to transition?

Question

Hello, slowly learning the animation tree. I animated one leg walking and then copied the animation to the other without offsetting thinking TimeSeek and Add2 in the AnimationTree would let me just blend them in Godot. But Transition turns the TimeSeek negative and even if its the correct amount of seconds (-1.0) for halfway through the animation they both still play at the same time with no offset when I run the project. Do I just need to offset it in my animation program, or am I just doing something wrong here?
here are my nodes:

Thank you! Any extra learning material is appreciated.

Figured it out actually! For anyone in the future: After you click the animation node in the AnimationTree editor you can see something called “Set Custom Timeline from Marker” Use that and make the Start Offset the offset you want and make loop move “Linear”.
