Characters feet sunk into ground after applying Constraints Video#9

[MacroLP]

Describe the bug
After video #9 Working on Constraint Bones my characters feet are sunk into the ground a bit. I know we tried correcting the "floating" feet. I downloaded and used your v5.0 source code for UE 5.1 just to make sure I didn't mess anything up in the code and yet the feet remain a bit sunken. Also noticing something weird with the hands and IK? maybe but only in simulation, doesn't show in the skeleton.

To Reproduce
just simulate.

Expected behavior
I expected the characters feet to be level with the ground like you had solved at the end of the video.

  Should note i'm using the community updated basic version of ALS. And also Unreal 5.1.

Additional context
Any help debugging this would be appreciated. It could be my version of ALS, an error on myself

I went back and re applied all the virtual bones as well and it still wasn't fixed. But then I wondered if it was that little bastard Manny_Simple again. I switched just to the simple mesh and the feet were fixed in play... then I switched back to SKM_Manny and feet STAYED fixed... I DONT KNOW. Weird.

It's an issue with Unreals internal retargeting system if you use the skeleton retargeting setting "animation" for the ik bones. Sorry I am currently not in front of UE so I do not know the exact names of the settings.

Sadly this issue occurs if you share a skeleton asset and have multiple meshes connected to it, which have different proportions. Then your ik feet constraints will be off. Consequently the ik foot system will not work properly of ALS and your character might be flying in the air.
