DDJ-1000SRT Cue Slip

I was at a DJ store today and ran into this same issue many times on both decks.

You can see I'm holding the platter with the same amount of force but the cue keeps moving. Even though, I was at a DJ store. I was using my computer, which has never seen a DDJ1000SRT. Using the latest v102 firmware and Serato DJ Pro 2.3.2 I'm on macOS Mojave 10.14.6
