Fuji gfx 100s II - why the strong evf noise in flash mode?

[Fuji guy]

Hello shooters!

Just got a Fuji 100s II mostly for portrait work with and without strobes. Using Godox system. 
two issues: 

1: when trigger on camera it refuses to be in M mode it always jumps back to ttl?? 
 

2: there is a substatial amount of noise in the evf and lcd when trying to focus. Not seen in the final picture but it is extremely distracting and annoying not to be able to see clear but instead going through “snow” have seen others with same issues! But no one had an explanation or solution!

would be grateful if anyone knows anything about settings or explanations that would help.

Thank you!

Point 2.

Because the exposure is low without the flash firing, so it's being lifted a lot for the EVF preview, hence all that noise.

Doesn’t happen in canon R5 that I came from. So thought it was flawed mabey? 
Fuji has a few settings in how to manage the evf live but none of them fixes it. 
furthermore do anyone know why it won’t stay in manual mode when shooting with studio strobes. It always returns to ttl. A flaw?

Change the Preview Pic Effect setting to off (spanner menu).

Thanks for your help.

another thing - 

do you know why the flash settings won't stay on manuel but always jumps back to ttl. SO annoying and practically makes the camera impossible for my use cases. I’m a godox user. At my seller I tried profoto trigger and flash and it worked but godox won’t work. 
can’t afford to switch to profoto.

there must be a solution.

anyone?

Are you using the trigger X3 F?  I have never yet seen this issue of the flash settings jumping back to TTL. This on various Nikon, Fuji etc over the last 2 or 3 years.

Am about to try a GFX 100SII next week with my Godox…...
