2D Tracking of multilayer open exr files

I am compositing in blender from a open exr animation export and want to 2D track a mask over the open exr export. I am finding that the tracker interface won’t read multilayer open exrs. Can anyone confirm that this normal?

Can’t confirm nor deny, but a workaround would be to use compositor and split out the channels you want to track to simple exr-s or png/jpg etc and do the track on these.
