itextsharp, label slipped down

Hi,

I have a PDF generating page, but I have a problem with the labels. The PDF has a fillable form and when I fill the lables with the itextsharp they slip down from the rest of the form. It is not much just a milimeter or so but we have bussiness cards and we can't use it like this.

I attached a pdf which has this problem with the labels slipped down. Check mobile and fax starting with 0 because the rest is fixed.

I have tried everything but the label won't go up a milimeter.

Please help if you can, thank you.

Best regards,
Bogi
