It all depends on which signature positioning mode you have chosen.
Automatic
If we do not find markers on the documents, a page intended to receive the signatures is automatically added at the beginning of the downloaded documents. This cover page will list all the signatories.
If we find markers in your documents, we will not add a cover page and will place the signatures in the areas delimited by the markers.
Manual
The signatures will appear in the document at the places you have defined, (page number and distances from the top & left side edges).
