So I bought something yesterday from the millionaire center, and my total saved amount still hasn't gone up.

So I'm thinking this probably was the free shop -- it might not even be every item in there, just ones that originated from certain shops.

Not sure if a lot can be done, but I check with a programmer.

I am pretty sure this is mostly due to the Free Shop. I've pushed a fix that makes it not count items from the Free Shop. That won't really be relevant again until December, but the fix is done at least for then.

Since you only had the card for one day, do you remember what purchases you made to bring it to that total? If it started out at a high total, it's possible you had a discount card at some point in the past, and it kept that total when you got this one.
