Some Wandering Trader NBT is reverted when Logging out of Game

Some NBT data associated with a wandering trader (summoned by commands) is completely reverted when logging out of the game and coming back. The reverting of the NBT also seems to be irreversible. The biggest example of this is the Offers NBT, where if you set a trader to not have any offers, relogging will suddenly make normal offers appear. This cannot be changed, even with /data commands. On another note, /data in general seems to be very odd with the trader after relogging. /data modify, for example, does not appear to work at all.

Are you sure the one you spawned in with command didn't just despawn, and a new one spawned in naturally?

The Offers tag reverted as a normal wandering trader's Offers.
If not be clearing his Offer, it will keep the same Offers, or else it will be replace a new random Offers.

The UUID is being the same UUID, so probably not naturally spawn a new one there.
Affects on 1.16.5

 

Can Confirm in 1.17.1

And being weird that,

it reads some of the data on the other map in my computer to replacing the display of air.
