rt | There are a lot of tools missing

Hello everyone.
I’m probably missing obvious things in the help again. The help is very extensive, but my knowledge of English is something else.
I understand that the thing I’m looking for is very simple, but it took me all morning to find where this option is.
We’re talking about the raw tab. For some reason, I don’t have the “demosaing” tools in it (https://rawpedia.rawtherapee.com/Demosaicing). How do I enable these tools, or were they cut out in new versions?

Which file type do you open? If it’s some sort of DNG from tools like Topaz, they are already demosaiced, so the tools are not available for them.

Yes, the files were processed in dxo pureraw into dng format before I exported them for rt.
It’s clear.
Thank you. Otherwise I would have been scratching my head all day)

DNG format may accept not only un-demoseiced image data but also demoseiced data. If you made demoseiced dng file, the situation may be like this.

It’s clear. Thank you.
