I take it you mean on your proof you get a bluish cast?
Or do you mean on your monitor preview?

If you mean on your proof, all the contrary... if it sees the matchprint
as yellower than the OCE paper, then it should place yellow on the proof
and give you a yellow cast.
But this should only happen in absolute colorimetric renderings.
Otherwise, you have a problem with optical whiteners in the OCE paper.
PrintOpen can compensate for this in software, to an extent. A uv filter
for your spectro would help more.

Using Kodak Colorflow Profile Editor, what should I adjust to fix this?
You only need to edit only the paper white tag in the profile, I don't
know if Kodak's software does it but many others do.

The matchprint we use here is "ultra white"; it's not easy to find a
paper up to it, since it's neutral without whiteners. Imation's paper
might be one of the closest, but terribly expensive.
If you are working with a more yellowish matchprint base, such as
"publication", then you could look to Mitsubishi's paper that is more or
less the same, and with very good printing qualities.
One of my favorites price/performance is Perfect Proof
(www.perfectproof.com) Semimatte, great handling drying and saturation,
but it has a lot of whitener so it's a pain to profile.
