Printer Dialogue Box: Subject appears in long vertical column

When trying to print an email with eM Client, the dialogue box pops up and the preview show the email's subject, To, and From lines in a long vertical column. This seems to only occur within the eM Client app and only on my Macbook Pro. I use the same email client on my Air with no issues. This is a recent development. I'm on Tahoe Beta 26.2.
