Pretty sure it's not actually a bug. If you're showing recent catalogue entries, then the custom fields are implemented as catalogue entries. One of the fields probably isn't showing as it likely is not set to display in category listings, which would be the case for main_multi_content output.

However, I will make it so custom field catalogue entries get filtered out from this block.

Yes, that's the result I was hoping for. If they aren't attached to an actual download they aren't particularly useful on their own (and incomplete, if not all data is being shown). I understand that I can edit the block, but I am normally reporting issues with the defaults. Thanks again.
