Two Versions of the City or Local Wage and Tax Statement (Copy 2) on W-2

It looks like I received two versions of the City or Local Wage and Tax Statement (Copy 2) on my W-2 from my employer. Boxes 18 and 19 on each show different local wages and local income tax, however, Box 20 has the same Locality Name "PHILADELPHIA". How should I handle this on my taxes?
