Hi everyone, Storyline stuff noted my issue and will try to solve it. And they adviced me the solution of this problem:
As a workaround, you can set all of your layers' properties to be Present as "Layer", and then also pause the timeline on the base layer. For the background effect, insert a rectangle with the color of your choice and set its transparency as desired. Here's a screencast of that workaround - https://sharing.articulate.team/GGueq1Zx
I set up all the checks and "Allow seeking - No" as it was in the Dialog.
Now everything works correctly, thanks!
Hope somebody will find it useful as me
