WOW! So you got those from us already?? That's good to know! Yours was sent on Friday, and for you to get it on Tuesday is really amazing!!!
The white blank cards are typical and should not count toward the five cards per pack. Card manufacturers started doing this a long time ago because people who could buy cards by the pack at hobby stores would search through to find the packs that contained the thicker memorabilia cards. Now, when you find these packs, the odds are that they will contain these blank cards and not an actual memorabilia card, which are obviously very rare.
About the box with only 23 packs, I just found this on their site:

What if my box does not contain the advertised contents for the box?
