I'm not aware of any case where an Atlas probe created an IPv6 ULA out
of thin air. Addresses are either statically configured or derived from
a prefix in a router advertisement.

So most likely the probe picked it up from an RA. Your probe is now up
for 27 days. So that's the time period where the probe could have
received the RA.

If the lifetime in the RA is infinite, then the prefix will essentially
stay there forever, or until another RA modifies the lifetime.

The easiest way to get rid of it is to powercycle the probe.
