[Artboards and bleeds]

I've been using AD for a month. I've been making two page marketing sheets of various sizes.

 

For a document, I created two artboards for front and back so I can see both at once. I setup bleeds which you can't see onscreen before exporting.

 

My questions are:

1. When I export to PDF with bleeds showing, my front page has printer marks but no bleeds while the back page shows the printer marks and bleeds. I definitely have the content going outside the artboard on both pages, so why would the back show bleeds and the front doesn't?

 

2. Should I even use Artboards at all for a 2 page document? It seems like some things don't work right with Artboards. Is there a better way?

 

3. When is there going to be a way to see the bleeds onscreen? It's tiresome to export and check the export just to check a bleed.

 

Thanks in advance.
