DCP-o-matic

Hello, I'm trying to make a DCP for a test screening of the short film I'm working on. The film was graded in Davinci Resolve 17 in Rec709 2.4 gamma. When I add our final render (ProRes 422HQ, 4K DCI Resolution) in to DCP-o-matic I do not see the same options to choose a color space conversion that I see in the User Manual. In fact, i have no option there at all. See attached screenshot below.

When I right click on my movie content and choose "Properties" I see that DOM recognizes the file to be in BT709 color space and that the Colour transfer characteristic is set to "Unspecified"

I am using the latest full release version of DCP-o-matic. Perhaps has this option been removed in favor of automatic color space detection/conversion? Any help or advice would be greatly appreciated.

Sadly you've been bitten by a common problem...

Go to preferences and set "interface complexity" to "full" and the option should return.

Wonderful, I assumed I was missing something simple like this. Thanks very much!
