I just applied to a job on Indeed and was instantly marked as "not selected". Is this some sort of fluke or what?

This is a strange issue I've never seen before. I'm newly out of school and in the middle of a job search. I saw a position in my field open up right around where I'm hoping and dreaming to move to. I applied to it, of course. The posting itself is only 4 days old, I meet most of the qualifications, and marked myself as able and willing to relocate and commute in the meanwhile (as it's a bit of a drive, but I'd make the trip to start while in the process of moving if needed).
When looking back under the "my jobs" section of Indeed, the new application for that job was there, however it was already marked as "not selected" with the little red X. However, I checked right after submitting my application. It was maybe a minute after clicking submit at most, not even enough time to look over the application. I received the confirmation of application in my email, and it's just so strange that I'm already marked as not selected. It's also Sunday night where I am... so unlikely someone has even seen my application come in yet. What's more odd is that the job posting is 4 days old, however under the "my jobs" application confirmation (where it says "not selected) it says "employer actively reviewed candidates 23 days ago". So... do you all think this is some sort of odd fluke with the website? Have any of you had this issue before, and do you think it may get in the way of my application being looked at? I meet the qualifications and Indeed has marked this posting as having "1-10" applicants only so far. What do you all think?
