We are wanting to change how we do a fitting (Hafele Rafix), we currently have 2 versions of the same fitting drawn up one that works with a flush butt joint, another that works with a 2mm M&T if we want a bit more strength / help with location. This has cause a few errors as we have had the wrong fitting selected for the wrong joint type.

From looking at the fitting page more we have noticed that there is an option to have the fitting used the recessed value. This does not seem to be working. Is there something else we need to do? In the 2 screenshots below the only difference is to have the panel going into a groove in the preview window. But as you can see it is not working on the version with the groove.

I have also attached a simple cabinet using this fitting, one side recessed one side flush, showing it not working correctly.
