Spreadsheet text formatting issues saving as PDF

I’m running Onlyoffice 7.4 on Windows 11
I have a multi-tab spreadsheet which I need to produce a PDF version of.
When doing a Save As and choosing PDF, most of it comes out fine, but one section does not - the size of the cells is wrong meaning that the text is truncated.
I have tried LibreOffice on the same file, and this exports to PDF just fine.

See attachment.

Any ideas ?

Hello @CSleightholme

Is it possible to share the spreadsheet itself so we can analyze it?
If there is any sensitive data, you can remove it to the degree where the issue with designated block is still reproducible. You can upload the file to cloud storage of you liking and share an external link to the file via PM for safety.
