Reverse rating scale ticks

Hello,
I’m trying to reverse ticks in a slider component. That is, I want the most right tick to be assigned the value 1 instead of 9.
I have tried doing it in the most intuitive way and replaced (1, 2, 3, 4, 5, 6, 7, 8, 9) with (9, 8, 7, 6, 5, 4, 3, 2, 1). However, when this change is applied and the experiment is running, it does not matter where I click on the slider, the marker is being assigned to the most right tick and cannot move from there. Even when I’m clicking on other ticks, the marker just doesn’t move.
I hope that I’m making myself clear. Does anybody encountered this problem and might have a solution?
Thank you

Hello Roy,

it works in this toy-example. You have to press space to end the routine.
