Adobe Dimension Save As puzzle

Hello, big fan of Dimension and just discoverd the updated version. Only gripe so far is saving my work. Had a look for duplicate posts, but no luck... Whenever I hit Save, rather than just saving in the background, it pulls up the 'Save As' pane, and eemingly have to overwrite the file each time? I don't see options to change in the File Handling settings? Any help would be much appreciated! Thank you.
