If you read the AdSense FAQ, or prior posts on the subject here, you will learn that Google will fill one, two, or three units depending upon its inventory. And it will fill them in the order it finds them in your html code.

Perhaps I wasn't clear on the point that the Google AdSense preview tool reveals that there is plenty of inventory to fill the slots.

There is obviously a disconnect between the Adsense Preview tool and the reality of G filling up all the 3 ad formats. It may be a temporary glitch, or maybe not. Unfortunately, we don't earn from the ads shown in the Preview tool - we earn from the ads shown on our site. So better make use of the collapsible script in order to avoid showing a big blank spot in your page.
We are also in a category where there are supposed to be an abundance of ads, but we have many pages where only one ad format is filled and the other 2 ad formats are not shown. You may also want to check out this thread:

I've put a second ad block on my homepage, so far just firing blanks.

It seems axiomatic that the mere fact that Google has inventory available does not mean that they will choose to exhaust it on your site, rather than spreding it across an array of AdSense publishers, even if it would mean "more profit for you".

Most likely the reason why they introduced the collapsible script simultaneously, because they know that they may not be able to fill the additional ad spots for many web pages.

I have the same problem. After placing second unit to my site instead of PSA's ads it just show me blank place... Really strange.
I have putted it down of the page to see what will happen.

Now i'im getting PSA's on the main block for the first time ever, and a blank for the second block. I must remove it until things settle down.

There seem to continue to be problems with the multiple ad presentation, though when it works it seems quite effective.
My earnings yesterday went to 3X what they had been on a daily average for the past month, I think in no small part because of the ads (and that's even with the problems that some of my pages had with them).
The system seems to really dislike the three ad approach, so I've backed off on that for the moment; the two-ad deal isn't perfect but seems to work better (at least for the sites where there are ample ads that appear available from the preview tool).
