My bars look a lot like your's... and probably like most others do...
I've come to the conclusion that my bars aren't broken, but rather, are fixed! :-|
There was a time when, during my backswing, there was little or no movement of the bars. Now, I suppose, they are shrinking (as they should) during my backswing, and if I use almost full power, there is very little movement remaining to be seen.
Some time ago... before I became "Legend"... the bars didn't start to shrink until I had my backswing power set. After a moment, they would then begin to move towards the center.
Weird. Seems like I had more "forgiveness" then.
I kinda liked it the way it was. :/
