It breaks when adding XML medatata to SSO IdP Metadata

I created a WP sandbox to implement SSO. When I add the XML medadata to the SSO Ido Metadata field I get the following error:

> Invalid array settings: sp_entityId_not_found, sp_acs_url_invalid, sp_sls_url_invalid

Here is the format of the XML I add to the field:
```

XXXXXXXXXXXXXXXXXXX=






XXXXXXXXXXXX=
