Zbrush 2021 Tpose/SubT

hi,
after updating to Zbrush 2021.
the Transpose Master tool under Zplugin starts to act funny.
I click the Zsphere Rig and Layer option before I go into TposeMesh.
after finish my posing. then I click Tpose/SubT.
Zbrush did give me a layer but not include the original pose.
it usee to work in Zbrush 2020. I wonder what step do I missing?

Thanks, this is a known problem which will be fixed as soon as possible.
