Losing formatting style. Anyone?

I am using the latest OmniOutliner 4.1.1 (v165.4.2.0.212611). Whenever I save the document and opens it again, I am losing its rows formatting style specifically when I chose the styles from the styles sidebar.
Please advice is that a bug or what?

Are you losing all formatting, or just certain ones? My guess would be that you’re saving in OPML format which doesn’t support formatting. If you hold down the Option key you will see a Save As option in the File menu and then you can change the format to OmniOutliner. Does that help?

I am using OO3 format. I am losing its rows formatting style specifically when I chose the styles from the styles sidebar. I dont know why maybe its because of the built in Stylish Theme that I chose?

Could you please send in to support an example file with step-by-step directions of applying a style that is being lost so we can see exactly what’s going on? Thanks!
