Snap LXD upgraded to 4.0.9 candidate yet pinned to stable

How it is possible? all servers are tracking stable not candidate.
tracking: 4.0/stable
4.0/stable: 4.0.8 2021-11-06 (21835) 70MB -
4.0/candidate: 4.0.9 2022-02-23 (22526) 71MB -

installed: 4.0.9 (22526) 71MB in-cohort

That’s just snap info confusingly reporting the state of a phased rollout.

4.0.9 is in stable (as of last night) but we started with 10% of users and it’s increasing by 10% or so every 6 hours. snap info may not show the accurate information until the rollout hits 100%.
