project file attached as requested.
Found the wrench that I had stuck into the works: 'Make overhead printable' in the experimental section was enabled.
While the 'make overhead printable' was definitively causing issues, I am still not getting the results I am expecting. I think there is a second issue at work. Here is a screen shot of the first layer preview:
You can see that the area of the blind ring (refer to the picture in first post) has two loops of 'helpers' which are screwing up the works. I have also included the project file.
The 'helper' lines only seem to be printed on the first layer as if they are there to hold the inside post in place. On the assumption that maybe the details were too small to print, I increased the depth and width of the blind channel with the same result.
Edit: For some reason I decided to go from 'brim' to 'skirt' mode under adhesion and the helper lines went away. Now when I had 'Brim' mode selected, I had also checked 'brim on outside only'. Does Cura possibly think that feature is a new model as the inside post has no connection to the rest of the model on the first layer?
Is there some option that I could enable to print with a brim but not have brims generated for these kind of 'inside' features ? (hope that makes sense)
Is this one of those situations where I have to adjust the model design to make it printable (small bridge on the first layer to attach the inside post to the outside)?
Another edit: I redesigned the model to have a tiny bridge over the blind channel which fixed the issue of the helpers. I am still wondering if there is something I can do in the Cura configuration or if model redesign is the only option.

If you can post a .3mf Cura project file it will be easier to help.
