Does it happen with other skins too? Looks like it's not because of your skin, there are multiple points which doesn't fit and something different is causing that.
(In the skin you gave me, the slider border colour isn't black as you showed in your screenshots (I assume you selected the blue colour, right?) and the slider track should have a little white way aswell, but that's not the case in your situation.) Even when you would have ticked beatmap skins, this white thingy in the slider track
should be there.
I hope someone else can help.
