Playback and Recording Level Toolbar are missing scaling and db levels

Hey, I have been using Audacity for a few months now, and love the simplicity around it. I am not sure what has happened but I have reopened a saved file and now my Audacity has the playback and recording meters missing on the toolbar., it is no longer showing the -60 - 0 or the coloured volume scale. Has anyone had this issue before and know of a fix? Cheers. [Screenshot 2023-12-13 at 11.17.42]
