Page added for signatures too large

Bonjour,

We use the mandatory Function & Company name (Account / Signature Preferences / Supplemental Parameters) in order to get an additionnal page at the end of the signed pdf.

Some of our signed pdf documents get an extra-large page format A3)  - our documents have 3-5 pages, legal format.

This only appears on some documents and started this week ( week of  january 31st 2020).
