I put unbranded gas in my 2015 Kia Rio and later my car jerked few times. Is something wrong in the car or the gas?

I have never experienced car jerk after filling up. This was unbelievable. I filled the unbranded because it was cheapest station.

Now that gas has all been used and I filled at wawa later. There were no problems or jerks.

So I'm not sure why this happened. Any reasons?
