I'm on 5.8.10 but there is an update for 5.8.10

But it won't apply the update because it thinks it's a downgrade:

Interestingly, no update is shown on my other instance of Nextcloud

Hello @jdaviescoates
Just ignore it for now.
Currently working on another Nextcloud update, https://forum.cloudron.io/post/130292
With that released there will be a new update anyway which should fix your issue.
