Hi CHERYLWALSH_826,
Could you try the following steps to set default open behavior for browser-enabled documents for a library?
- Go to a library in SharePoint Online.
- Click LIBRARY > Library settings > Advanced Settings.
- Under Opening Documents in the Browser, select Open in the client application.
- Click OK.
In addition, for "I do not have on my feature page the "Open Documents in Client Applications by Default" section/item" , may I know if you are using SharePoint On-premise instead of SharePoint Online?
Regards,
Shirley
