Field Settings - Validation - Phone. If you select Canada and save it. The form will display the United States. I went back into settings to double-check the settings were still set to Canada, while the manage form view displayed the United States.
Ultimately, my goal is to automate a dropdown with logic that presents the same country phone number with its area code. I have the logic down-packed; hopefully, the Canada bug I uncovered has a fix. Heads up, I tested 4 countries, and the logic worked for all four.
