Why is my GPS in the past?

[AC Question]

I travel every day and travel large parts of the country. My GPS location is frequently shown as locations I haven't been to for days. For instance, my phone currently believes that I am in Duluth Minnesota, a place that I was at almost a week ago.

I have a Nexus 5X, through project fi, that is completely up to date, and the problem has been very recent. It has only been happening for the past week or two. Any advice on how to fix this problem would be greatly appreciated.
