Email order missing phone number for months

For a few months my order emails have been missing the phone number of who it’s shipping to. They were always included before and it’s a required field at check out. when I go into word press the phone number is there but for some reason it’s no longer printing on the email. We are a florist and need that info to process our orders in our point of sale and without it we are taking extra time looking it up. If anyone knows an easy fix or a box I might have to check or if the theme is messing up. I’m not a coder I’m a florist so anything code related might be above my pay grade HA! any suggestions welcome. Thank you all in advance for your help!
