EPS Export Issue: Losing Pantone color. Imports as gray.

I prep files for printing in promotional products industry. Have been using DRAW for MANY years. Recently upgraded to X7.

When I export Pantone colors in a file, then import the file, the Pantone colors all are a CMYK gray.

Not sure if this is an import issue, or an export issue. Either way it's a huge issue. I can't send files to have them printed unless I know they're correct.

Help!
