DMS in CBAT: Phone # format for DMS sign-up

I am using the same candidate for both 2-way texting and DMS beta testing. For 2-way texting, the candidate phone number needs to be in international format (prefaced with +1 for US).

When I went to sign-up for DMS to view my test document, I am getting an error that my phone number is not a 10 digit #. While I was able to move forward after removing the #1, it would be nice to have consistency in the phone number formatting.
