Specific camera settings for raw defaults are lost when converting to DNG during import

I have set raw defaults with specific camera settings to be used on importing, like so:

This works as intended when I import raw files (from the Sony ILCE-7RM4): the preset for the camera is applied. However, when I import the same raw files and select the option "Copy as DNG", the import preset is not applied and I have to apply them by hand after the import action.

Interestingly, after having done the import with DNG conversion the settings have changed and look like this:

Note that the Default for the specific camera has changed to "Adobe default".

This looks to me like a bug, or I must have missed a specific setting. Any help is appreciated.
