Out of 23 gmail addresses, 3 have one breach each, (all different).
Not too worried as it was for sites that were unimportant, 2FA is used on the gmail accounts and any important sites.
That site is rather limited in it's checking algorithm though, eg.
All the same address as far as email is concerned but the checker regards each as being a separate entity, ie. firstname.lastname@example.org is compromised but as far as the check is concerned, email@example.com won't be.
They need to strip out all the irrelevant characters before checking, both from the input address and their lookup lists.
