Windows Central Question

I bought a Lumia 640 in China as my office phone and every time I manually enter a phone number, e.g. 185-12345678, it always shows up as 1(851)2345678. I change the Region, Location and Language to different countries and it still remains the same.

Open the Phone App > ellipsis (. . .) > settings > International Assist should be toggled to off
