Sorry to resurrect a post that's been inactive for a while, but just thought I'd update in case anyone else is scrolling through looking for answers...
We ended up scheduling an appointment with our field office almost a year ago (when I originally posted looking for advice) and spoke to someone in person who pulled up our case in the system and told us that we didn't need to do anything. The key was, when we went in we had been married for more than 2 years, so the officer told us that seeing as we would qualify for the 10-year card at that point they would not require us to get a new card or go through the removal of conditions process. We figure it's more hassle/potential expense in wages for them than it's worth to get us to go back and file for a corrected green card and then removal of conditions that then have to be processed, despite the fact that we also didn't have to pay the $600 fee for removal of conditions.
So, my advice is, if you notice that you have mistakenly gotten a 10-year card and you feel that you need to speak to someone official to make sure you'll be alright, wait until you're past the point that you would qualify for the 10-year card as they're unlikely to make you change it at that point. We just filed my husband's N400 online on 04/17/2018 and have already received NOA and the biometrics appointment (though we can't see the biometrics date/time yet), so hopefully it all goes smoothly!
