I have checked this and noticed it only happens when you have the mask option enabled, if you disable the option the phone number will display properly.
I will report the issue to our second level so our developers can investigate it, we will let you know as soon as we get any update about it.
We are sorry for the inconvenience we may have caused to you.
Problem should be fixed and phone number field submissions can be viewed correctly now. Please check it and let me know if any issue arises again.
