Export as PDF does not keep the word document format

Hi

We have started using the OOB Export to PDF in Dynamics Online v9.1. 

When we use it to generate one of the word templates as PDF, it changes the format. If we export the original word template, the document looks ok. However when the document is generate as PDF using this Export as PDF button, the layout changes.

In particular, my problem is that in word, a table with quote lines is divided between multiple pages (this is what we want). However when the document is generated as PDF from Export as PDF, it moves the table to the next page. 

Do you know how I can fix this problem?

Thanks

Teresa
