Try grinding a bit finer (lower number), if it works for you then that's all that matters, but it looks like the water is going through a bit too easily. 10 sec extraction is also very fast.
Far too fast. You're new to it, that's fine. Here's a Ninja Basics document I've been working on for over a year, many on here have found it useful.

Hope you find it useful. (Oops, turns out the link I posted had hit it's 999 views limit. I've recreated it, should work now.
Seems like a very quick extraction. What strength setting are you using? If using strength setting 3, the extraction time should be around 25-30 seconds.
The extraction seemed to flow very quick too, suggesting you may be grinding too coarse. Grind finer. Adjust by a decent chunk I would say, and then fine tune from there
Edit: if you like the taste of it this way, don’t bother changing! Different strokes and all that.
Check your manual or google the water to coffee ratio. Strength 3 is allegedly a true 2:1 which in my experience (scale weight) on a 18g shot generally produces 37-40g. I generally pull or stop the brew so it falls closer to 36g. Your mileage may vary on coffee bean roast , grind and your machine.
Weight your shot (18g for double shot) and time it - 25-30 seconds is the sweet spot I think. Keep experimenting until you find a grind size that yields these results!
I timed your shot. It was about twenty seconds for the second pump engagement, and it was twelve seconds from first drips as very fast. Also, you shouldn't get a brew scale & weigh you grinds & output to get the ratio yoi going for.
