My AIS is confusing me.

So here’s the situation. Since last week, I was on Step 4, so my AIS had shown that a decision for my application had been made and a letter was sent out that week. I check it today, and I’m at Step 3, and it says that they are reviewing my application credentials. Is this a system error? What is going on?! Answers greatly appreciated.
