That's great! Don't forget to formally declare your support for R&S so
we can add your IdP to the official list of IdPs that support R&S.

That's not surprising.

You could raise this issue at the contact email in metadata but it may
be easier just sending a single value to the SP.

I'm not sure what the concern is. Why not release a single email
address to all external SPs?

I'm not sure what you mean. Do you mean two attributes with the same
name in a single assertion? I wouldn't do that. That's probably the
least desirable of all the options you have.
