Hi davisnz,
Can you please export your pipe and upload it here for me to check? You can do it by clicking on the small arrow next to the <<Save>> button and choose "Export yo .pipe file".
There are cases that require us to make heavy configuration with Parser Code and the likes before we could make Pipes fetch the content accurately, and it's kind of hard to offer a solution when I have to go blind on the data construction on your source.
Or you can show me the link to your RSS Feed.
With best regards.
