extra space above a comp statement header

Summary:

Content (required):

We recently noticed that extra space above the header on our comp statements. The header on the RTF template looks good, no space at the top or on the right, but when we generate statements in PDF format a narrow white line appears above the header.

Any ideas how I can resolve this?

Thank you in advance!
