Hyphenated Last Names in Green Card

[Mexsd32]

Hi! I have a question regarding my new greencard..i received it a couple days ago but i noticed that my last names came hyphenated. My name in my foreign passport is: firstname + lastname1 + space + lastname2 but in my greencard is firstname + lastname1 + hyphen + lastname2 .. Is this a problem? Should i ask for a replacement to correct this? Should i change my ss card to hyphenate my last name too? Please advise. Thanks
