Mac Mail export message as PDF - cuts off right side

Hi, I am wishing to save certain email messages as PDF files, e.g. for tax receipt records. I have no need to physically print these off.

I select a Mail message and then File > Export as PDF... , then I choose a place to save it.

Mail exports the PDF, but it is cutting off the right side of some emails that have images included. In particular, emails from Apple are doing this.

See screenshots. Any suggestions please of how to remedy this? Thanks.
