EDGELEC 120pcs Breadboard Jumper Wires

I ordered this one: https://smile.amazon.com/gp/product/B08J9WN356

It's the 3.1 version, and it works fine for me. I would try re-flashing the firmware maybe?

Since it came with the extension cable, all I did was swap the short cable on the BLTouch (it shipped already connected) with the extension cable, then I grabbed some male-to-male breadboard jumper cables, matched the wires up by color to the dupont connectors on the BLTouch extension cable, then attached the short BLTouch cable to the other end of the jumpers, again matching up the colors.

I got the L10 pro. Do I nee to get male ended dupont cables to plug into the robot? The guide says the pitch is 2mm on the Dreame. Would the male pins from these cables work or are they too big? Sorry this is my first time working with dupont cables / jumper wires so I'm not too familiar with how things fit.
