Paul,
In your screenshot, the vertical grid line nearest the center is at 910.000 MHz, the nearest "round" number.
Does that explain the offset you see?

Question, why when I set a center frequency of 910.525 MHz on my Nano VNA-H4
(as I did here within this image) then I set a marker for 910.525MHz, they
are offset from each other?
