I double checked. There is absolutely no Sedo MLS premium set. It is only Sedo Basic. And I specifically wouldn't want MLS premium anyhow, given my what I thought were former experiences with the Afternic FT.
Is Sedo now part of the Afternic FT system?
Dynadot appears to have the best system for turning Afternic FT on or off. Are you certain you found a way at Namecheap to turn off the FT? I had to go through customer service and their tech support. It was not an easy process with them.
If the spurious listings are going to be permitted...
