I wouldn't be concerned. Not everyone gets approved in the exact order. My app was received Sept 18th and I have the exact same information as you (it appears in GC Key if you don't have a rep). There aren't any red flags, I haven't had any additional requests, etc. And generally, from what I've read, IRCC is unlikely to provide you any additional information until you hit the one year mark, so even if others get approved or October gets approved, you're not likely to get anywhere until after Sept 20, 2020. Some applications take longer to process for reasons no one can parse from the outside, so there's lots of reasons why someone might get their app finalized before you, even if they applied after you.
Definitely keep an eye on your e-mail for an update from your representative in the next couple of weeks, hopefully you'll get approval in a timely manner!
