@inovelli-enjoyer I think that is because we are moving the mode select options to their own endpoints. The duplicates are the old entities. I posted this in this thread somewhere:
Note: The mode select clusters were moved to their own endpoints (20-27) to better conform to the standards. This (temporarily) creates duplicate select devices. Restart Home Assistant and the “old” copies will show up as Not Provided devices (greyed out, dead) entities. Go to entity tabs and filer on Domain = Select, Integration = Matter, Status = Not Provided and you should be able to bulk-select and delete those.
