This is a new forum layout. Some posts that have June 2019 dates are really older posts from the old forum that got moved over. So they might be for prior years and not current info. When they migrated over the dates got changed to June 2019. And the screen shots got deleted.
You need to close the business properly. Or if it transferred over there is a special way you have to delete it.
