I'm experimenting around and I was recommended to use Cura to slice my models. I was messing around with it and was having some stringing, so I started to try messing with the retraction distance and speed. I very quickly realized that for some reason the speed is capped at 40mm/s. I'm not sure if that's a printer physical limit, or if Cura is just being weird. I tried adjusting settings that might affect the retraction speed setting and hoped for some miracle fix, with no avail.

Any ideas why this might be happening?
