Hello,

We have checked the slider and it works properly: https://prnt.sc/q642vk and https://prnt.sc/q6430t

You have two equal sliders perhaps you edit one and show another one please check: https://prnt.sc/q643nd

As for the blocks on the slider, there is the option to create a global layer which is applied over all the other slides. Here is the screen how to get there and edit: https://gyazo.com/b34b7f211ba20a224c315abfdac41719
