Zoho CRM / Sign - document number are not homogeneous

Zoho CRM / Sign - document number are not homogeneous

I create a quote in Zoho CRM. The number is created automatically.
Then, I clic on the button "Send for Zoho Sign"
The name of the document is generated automatically.
Unfortunatelly, I always have a difference of  4 in between the numbers.

The quote xxxx017 on ZohoCRM become quote xxxx013 in Zoho sign.



I tried to delete everything, desinstall, reinstall.
The the difference is still there.
What could I do to have homogeneity between both platform ?

Thanks,
