About website logo duplication in expert mode

[mpenglong]

When I create a new site by directly copying one more site backup and data backup, I find that the logo (I think he is the site logo) in expert mode will be duplicated with the previous site, I have tried to uninstall and reinstall, and it is the same logo, how can I solve this aspect? I have thought that I should wait until the site is officially online before installing cache master, it may work, but there is no test environment to test it, this is an idea
