Install, uninstall and install again 'Omega' in appearance

I've installed, then uninstalled and then tried to install Omega 8.5 back again. The following error was received:

Unable to install omega, breakpoint.breakpoint.theme.omega.all, breakpoint.breakpoint.theme.omega.mobile_landscape, breakpoint.breakpoint.theme.omega.mobile_portrait, breakpoint.breakpoint.theme.omega.narrow, breakpoint.breakpoint.theme.omega.normal, breakpoint.breakpoint.theme.omega.wide, breakpoint.breakpoint_group.theme.omega.omega, responsive_image.mappings.omega_picture_mappings already exist in active configuration.

I need to look further into it, however if someone else has any insight, please share. Thanks
