Seekbar/Animations with states and layers

Good morning. Someone please correct me if I'm wrong, but it seems that Storyline states and layers do not play nicely with the built-in Storyline seekbar. I have a screen where different parts of an aircraft are highlighted in sync with the audio. I have implemented this using states and also with layers, but have found with either that when the user begins scrubbing with the Storyline seekbar, all bets are off, and the states or layers just remain what they were, even if I scrub to a part of the timeline where a new object changes the state to a different image/view, or to a part of the timeline where an object that changed the state has not yet appeared. The end result is that I am now doing it the old fashioned way, bringing a different image on screen when needed at specific points in audio, and taking it off, as shown in attached. To be clear, this is specific to the seekbar. All is well as long as the seekbar is not used. Are others having this issue? What have you done for a work around. Sadly for me, since our company is so dependent on the seekbar, layers and states, which are considers one of the most powerful features of Storyline, are essentially useless for syncing imagery with audio. I'd be interested to hear your thoughts.
