I have the same Problem.
I play only in Windows Mode.
I use a Monitor with 4k in 21:9.
That mode is even different from that modes I can select.
Both damage shows are not more moveable.
I use every time the newest modpack.
It is a new issue since some versions ago.
I use the modpack in german.
Why is that no more free movable, that was the best solution.
What I have to do if I would both tables side by side?
