If you want your resulting mask to be those areas/pixels which are both in the drawn mask and in the parametric mask, then it should work, but as above, do the para mask first. (And first reset the module in case it’s remembering anything from your previous attempts)
If you want anything else then good luck!, it’s quite difficult or impossible. There’s a bug report about the “inclusive” setting here

There seems to be a problem … with the Combine Masks setting of "inclusive" when working with a parametric mask plus a drawn mask. Looking at the manual, 3.5.3.4 "combining drawn & parametric masks", "inclusive" is an "OR" operation and the maths described means any pixel in either or both of the para and drawn masks will be in the resulting mask. However I'm finding this doesn't work. I think "inclusive" is useful, allowing a para mask to be expanded with brush work.
To demonstrate: take any image, add an exposure instance, choose para+draw, create a para mask (I did hue, hz).
Now draw something that's not currently yellow. All yellow disappears; ok.
Change "exclusive" to "inclusive". Now the whole image is yellow. I would expect the yellow now to be the para yellow plus the drawn area.
and I’ve proposed a revamp of the interface here
Masks are a great part of dt, especially parametric ones IMHO. I think the interface could be improved though. I use masks but find the functionality somewhat opaque and difficult to use. I see the following areas which I think could be improved -
parametric masks are not well integrated with drawn ones
there are too many buttons, it’s confusing (e.g. inverting masks)
the GUI does not help me work through the operations (e.g. Filmic has tabs which you can work through in sequence)
the inter…
