I saw in another topic thread (now closed) that someone had problem a problem with the slider looking different and I had the same problem.
I ended up knowing what the problem was and it’s that when you scale the bar it will also mess with the child objects. Try to set the slider objects scale back to 1, 1,1 and then use the width and height values to change it’s size. If that does not work (you might have messed up to many values in the child objects to fix it) try to remake the whole thing but just do what I just suggested and it should work.
