Creating iso adaptive preset with technology preview on in ACR and including AI denoise/Enhance

Hi, 

Does anyone know why my option for iso adaptive presets is not available when trying to save an iso adaptive preset when having the technology preview turned on in ACR? I have the latest version installed. 
Is it because I have technology preview turned on or some other issue?
It seems to be possible to create other non-iso adaptive presets.
This is only valid for ACR with the technology preview turned on. Not valid for LR Classic since the option is not available there within the Detail section in presets on CR3 files.
Thanks in advance
