Color difference when viewing PDFs in Acrobat. Mac Preview view is fine

Whenever I view a document in Acrobat, the colors are wrong. I'm going out of my mind, because I can't find the problem. The problem occur both in the new and the old acrobat

I work only in AdobeRGB. When exported, I include the color profile. When viewing the PDF with preview, everthing looks fine. But in Acrobat, the colors become dull. I've checked my acrobat settings, and the RGB mode is also AdobeRGB.
