Multiple SAML authentication domains not working

I have configured two SAML authentication domains ( saml_auth_domain_1, saml_auth_domain_2).
SAML authentication working fine with domain_1 (order:1 ) , but when try to authenticate with domain_2 ( order:2) it is failing. SAML response is always validating with the order:1 configuration, so authentication failing.
Can you please help me if I am missing any configuration ?

SAML response for domain_2 authentication contains ( entity_id: ####/exk2a5dqy6V91kXy24x6 ) but this response got compared with domain_1 entity_id , not with the domain_2. so the validation is failing.
