Problems updating HA


I have installed HA as a docker container on a Synology NAS. Everything went smooth and I got right into the UI. I then saw that I had version 20.2 and wanted to update to 28.2. After I have run the update the hass version is shown to be 28.2, but I cannot get the UI to show the correct version? It still shows me the notification for update is available and inside the devInfo it shows the version to be 20.2 or 14.2 (tried installing it twice from two separate docker images).

What am I doing wrong here?
