RC9 (2.9.9.9) - Bug of the saving user styles or not?

Added user styles are not saved for the new progect.
Is it correct or not?

Custom styles aren’t saved globally automatically. I know in the Mac version you can do this manually by setting the global styles defaults to include your custom styles, but it doesn’t look like this is an option in Scrivener 3 for Windows.

You can always import your styles from one project to another. Use the Format > Style > Import Styles… menu command (or click the ••• button in the floating styles panel). Locate the project folder you wish to import from in the file chooser and click ‘Select Folder’.

Or to creatе a tamplet with the needed styles. Thanks.
