Storyline: objects on video do not play when user rewinds/fast-forwards

Hello! I'm quite new to the program, and I was wondering if anyone could help me with the following: 

I have a video in a Storyline course, and I wanted to make some text appear at certain points throughout the video.

I've got those text bits attached to cue points on the timeline (all of this on the base layer, although I tried creating separate layers for text parts too), but they only appear if a user patiently watches the video from the beginning to the respective cue point. They don't appear when the video is replayed or if the user fast-forwards through it.

This is really inconvenient for learners, and I'd like to avoid using video editor to fix it for corporate reasons. Can I somehow resolve this issue in Storyline itself?

Any advice is much appreciated, thank you!
