WIX - form submissions

Does anyone know why on my form where clients can submit their name, phone number, email etc. the form will not accept “778” area codes and says “Enter a Valid Phone Number”, although the number is valid?! Is there a way to disable this so clients can add any phone number without this error message?

Using Wix Studio Editor

Yeah, but when they put full phone number they will not see the error message then

Hmmm we have 10 digit phone numbers though (not11)? I am putting in the full number ex. 778-111-1111 but still getting error message.
