If what you've got is still at the revalidation stage (not final emailed certificate) then it might yet change!
Last year, I got "must carry distance / must carry reading" and I've never needed distance. Freaked out a bit at the thought of having to correct the official record, but medical branch assured me it was the way they process any initial vision correction issue - they put everything on the interim record, then fix it later! And they did and I didn't need to do anything.
But talk to medical division - they're generally pretty good with this kind of thing.
