Converted to 2017 can not select distance shadow mask

Hi,
Converted our SteamVR game to 2017.1, seems most things work, thats a first for a Unity major update (moving from 5.5.4 to 2017.1) :smile: I want to use the Distance shadow map but Its not available

What am i doing wrong?

As per the release notes:

3143770--238637--upload_2017-7-13_14-21-44.png

ah, nice, nothing in the docs, or I missed it

Maybe you can tell me why the reflection probes are all messed up?
