Lengthen Fields in Books Invoices

Lengthen Fields in Books Invoices

Our Project Names sometimes extend longer than the field in Books Invoices. I have tried for a couple of days to change the field length with no luck.  Attached is a photo of what is happening. The name of this particular Project is Texas A&M Athletics Training, and you can see it takes up two lines. I would like it to all be on one line. Some legal cases can take up to 4 lines. 

Thanks in advance.
