I see this problem too, and also in the upgrade to version 29 rc2.

Please post the full output of occ integrity:check-core.

Each time I have to take the extra step of deleting them before installing the new package.

Seems to be a Docker problem.

I’m not running docker.

Can you find the files somewhere? Make a search for the files in your Nextcloud folder. Also it is a beta version. Maybe you can create an issue at Github if it is really a bug.
