Sorry to hear the trouble remains. We'll have our findings here logged.
Internal Reference: ODNT-11951
However, the question remains: Could some mechanism of the "Reset the contents of my docks" button allow you to create new docks without the same issue?
I understand if you are hesitant to clear your docks in this manner, but it would seem useful to know if that exact button before creating a new dock has a desired outcome.
Thanks for posting and best regards,
