I use a PDF Template file which contains only one page to fill some labels texts inside.
Which is weird is that all fields are replaced correctly, only one doesn't.

Here on the picture I write a text in the first left-top label text box directly in PDF file, and it will show the text on all TextBoxes. But on my code behind (csharp) when I set the Text value for the PdfTextBoxFieldWidget it replaces only the first one in the left-top label. Why is happening this?
