Checkout showing "pick up" when it should say "shipping"

Hello, i’m looking for some help here. i’m not sure why but at checkout it shows “pick up” instead of shipping sometimes (i can’t replicate the problem with certainty of when it will happen, however when i go to test in an incognito window it shows “shipping”)

Hoping someone can take a look and help me out!
