Hello, I want to add an external test, but I encountered an error when creating the test information. The error message shows that the phone field needs to be filled with only numbers. The following is the error screen This page has one or more errors. Please make sure the contact phone number contains only numbers and try again. Cannot save name because there are other invalid fields. Cannot save last name because there are other invalid fields. Could not save email because there are other invalid fields. Has anyone else encountered the same situation? Thanks.
