Web Styles change not sticking

When I change the background and text color in a web style, save and close a project - then reopen it, the style change reverts. Is this a bug or is there and extra ‘web style save’ step I am missing?

Found a similar thread. Re-posted my question there…

Think that bug has been fixed for an upcoming release
