Auth0, SAML logout - NameID changed to lowercase in SAML logout request

hi all,
Have Auth0 as IDP, in login response Auth0 passes to SP SAML response with NameID in both lower and upper case, but upon SAML logout - SP provides NameID all in lowercase and the logout fails.

Is it possible for Auth0 to accept NameID all in lowercase in SAML logout request ?
thanks
