Switch direction of the position slider.

[Victor-41]

Hello, first of all, thank you for this lovelace.
I want to change the direction of the slider, but I have to click twice until I can see the slider change its position, then I click "Save" and nothing happens.
I can see in Yaml "rtl_position: true" but the slider does not change position.
I tried to uninstall and install again from HACS, but it doesn't work for me.
I have updated home assistant to its latest version.
What can I do?

Best regards,
