import created new site in multisite

I imported an .xls spreadsheet with our members. I, apparently, had the site name in lower case while the actual site is in Uppercase letters. So now a new site has been created in which these users have all been imported as users.

Unfortunately, the site that I wanted them in, they are NOT listed as users although they are listed in the membership plugin users.

Is this the way it's supposed to work? If not, how can I move them out of cava and into CAVA?
