Problème d'affiche de texte

Indeed, just like @Tariq Ahmad said, this is pure guesswork without inspecting the file itself.

In addition to the options he gave there obviously also are the options of an error in the PDF or of a bug in one program or the other.

Hi @sylvain30003306wegu, 

Thank you for reaching out with your question. 

It is hard to suggest anything there could be multiple reasons for it:

- If this is a form - there may be a script on some event.

- It may be how the form or file is designed

If possible, share the file with us and we will take a look and share our observations.
