nameid-format:unspecified

Hi everyone, I've been stuck for a few days and can't figure out the problem.

When I upload the metadata, it shows that the format is being passed:
```
urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName
urn:oasis:names:tc:SAML:2.0:nameid-format:transient
```
but again, I don’t understand why this is happening:
```

7

```
I’m going through all the options in the identity provider, and it always returns unspecified.

Even though I’ve tried using all the standard NameID formats, it always returns unspecified.
