Lightroom for IPad, sliders jump when I let go

When I go to move a slider like contrast for example, I typically click and hold somewhere on that slider that doesn’t cover the circle so I can see where it’s moving, but when I let go now the value jumps usually by around 5.

So I click and drag with my finger starting on the line (not the circle), I drag my finger to let’s say +6 contrast, and when I let go it jumps to +11. Doesn’t happen when I click and hold right on the circle but is just a little annoying that how it used to be.
