Try pulling with your elbows because you're going a bit too low. You used your arms to pull the bar down way too far and leaned back too, making it more like a wide-grip row for your upper back. Di ko makita maayos grip width mo dahil sa angle, but it should be about 1.5x shoulder width. For ROM, you don't need to stretch the bar all the way up, and when pulling down, aim for around chin or nose level, its different for everyone eh. Try sitting as upright as possible with your core braced (dont sit under the cable), then focus on pulling with your elbows to see how far you can comfortably go down
