Phone Number No Longer Populated

When I view a client's account and click on their email address to send a message, the client's phone number is no longer populated in the SMS section to send an email/text if I change the email to be sent. 

The phone number is properly populated with the default message that pops up. But, the phone number changes to just "1" when I select a different message from the list.

It replaces the phone number with just a "1" whenever I select anything from the dropdown other than the initial email that pops it. It doesn't seem to matter which once I pick from the list.

I still can't duplicate any issue with this. I'll make a note of it.
