Zoom axis centre postition not correct in some modules

In some modules, if I touch my zoom slider axis when it is centred, it jumps away from the initial default postion, usually haevily zoomed in. I have to adjust it by zooming back out.

This only happens in some modules, e.g. Black Shark, Spitfire. Perfectly OK in others, e.g. Hornet, F-16.

Could this be related to snap views somehow? Is it possible to define the middle zoom axis view somehow?

This is really annoying me, especially as my Virpil slider has a centre detent which tends to snap back into place if the control is fairly close to centre.

Any help appreciated.
