Nextcloud docker Version wrong version

I hope you can help me, but something was gone wrong with my update of the nextcloud.
I have updated the nextcloud today with a docker-compose command and it seems, all is correct. But at first in the meintance mode the version was shown 20.0.4 but the right one should be 20.0.5

The image was downloaded correctly and the nextcloud starts now and it seems all is ok, but it show me all the time, there is a new version 20.0.5 and I have installed 20.0.4

I have shown in version.php and config.php and in both files is version 20.0.4 but it no longer pulls a new image with the docker-compose. what can I do to use the actually version? Do I something wrong?

Thank you for helping me
