Free Text Box problem

Hello All

I recently purchased PDF Fusion and I have noticed that on some occasions when I create a 'Free Text Box' to enter wording on a PDF Form that the box created has 2 lines at the top (horizontal) of the box.  And when I enter text into the box it displays OK but it does not show up on a print preview nor when the actual document is printed.  I can't get any assistance from Corel as I can't find their page for sumiting a Tech Support question anywhere.

If anyone has come across this problem and knows how to resolve it I would be most grateful.
