Why is my gps and weather location wrong, galaxy s7

[AC Question]

For some reason, my phone says i am in Warwick, NY, and so does my gps. It might take a while for it to change back to the correct location, but it's only short term. Mind you, Warwick is 70 miles north of me in a different state (i live in Central NJ) and i have never lived nor even been there, or the surrounding area. Please help.
