Video Tracks Locked in Fairlight Won't Unlock

Guy's my video tracks in Fairlight.are locked up sliders won't unlock to make them thicker to unlock.
Audios I can adjust up and down but my videos and Effects I can't unlock them jammed up.
Cut and Edit page are all unlocked and okay.
I can't grab the lines to move either. I did a restart Resolve no luck.
Going to restart system to try that.
Appreciate Thanks, Cliff

You cannot change the size of the video tracks in the Fairlight page, they are there for reference. If you want to see the video open the scrollers.

This is using two screens.

Charles thanks for the information appreciate! This was my first time using Fairlight I learned a lot by watching the Blackmagic videos. Fairlight Audio Production 1 and 2. For some reason I felt you could move them down as well as the Audio.
At least I was able to learn techniques to adjust sounds in my video.
I only had myself making a Microgreen Smoothie with The Nutribullet blender. I was able to adjust my own Dialogue, Blender, and added background music.
I have had some weird issues in Version 17 Studio at times.
Where others haven't seen the issues. Now with new updates I finally see all the Scopes showing up.
I feel it might be my older Windows computer.
I will continue to view more videos and read the PDF's in Blackmagic.
Thanks,
Cliff
