Latitude & Longitude doesn't validate

[rebootcode]

Even with the correct value, the latitude and longitude don't validate correctly. Below is the used value:

latitude: "51.50975743908446"
longitude: "-0.09299784755596675"

Error:

The latitude field must contain valid latitude

The longitude field must contain valid longitude

Rules:

"latitude":  []string{"required", "lat"},
"longitude": []string{"required", "lon"},

Passed Rules:

required value is passed but "lat", "lon" rules are not.
