Exporting 'Comments' field completely

Hi,

We’re exporting the purchase order data from our V4.2 but ‘Comments’ field is not being exported fully.

When we export the ‘Comment’ field it only pulls the first line data and is missing the next two lines (see below highlighted in yellow). We’d like to export the whole field for all POs. Any idea how we can somehow get it? I’ve played around for a while but can’t see many options from the front end.
