Sending multiple packages via leboncoin for the same sale

Hello,

I have a question about a shipment I need to make after a sale on leboncoin.

I sold a lot of books that a buyer has paid for, but when I ship them, I have to make 2 packages because it will be too heavy if I only make one. However, when I print my shipping label, it says package 1/1.....

Should I print the label twice and stick one on each package?

I asked the same question on the help service of the leboncoin site, but I'm still waiting for a response for several days, and I'm going to reach the maximum deadline to send my sale.

Thank you for your reply.
