SDR BT.709 converted to BT.2020 HDR with full or partial copy

Using Nvidia encoding with RTX2060.

On UHD disc (Jaws, Spears & Munsil) with mixed video format like main movie in BT.2020 HDR and extras in 1080p SDR - extras are converted from BT.709 SDR to BT.2020 HDR. It's very annoying.

I'm getting the same result. Even on main movie when it's BT.709 it converts to BT.2020..
