BMPCC 6K Banding/Flickering footage

Hey guys
Last year I shot a short film on the BMPCC 6k.
In offline exports, everything looked fine, but now when I imported it to resolve, there's some distinct horizontal banding/wavy horizontal lines on top of the footage.
I'm uploading a sample for you guys to see -

*EDIT*
(If you'll watch from the link it wont be seen because of the Google drive compression.
Download it and you'll see it)

I searched online and found many possible reasons for this to happen -
- Wrong shutter settings
- Rolling shutter issues with certain lightning sources like LED etc.
- An electricity issue when connecting the BMPCC 6K to external battery.
The thing is, in some scenes we used the same camera settings in different shots, but only some of the material was "damaged".

My question is -
What do you think is the reason for this phenomena?

Further than that -
I did manage to remove it to some extent with noise reduction in Resolve, but it comes at a cost of loosing sharpness.
If you have a recommended plug-in\effect in any software there is, would love your advice.

Cheers.

If Resolve Noise Reduction helped, based on the other recent thread, I’d be tempted to try Neat Video Denoiser if that’s an option.

Definitely looks like LED banding. My Philips Hue lights would band at anything other than a multiple of 50Hz which I found strange in the US. The same banding doesn't seem to affect the key light which is flickering/strobing by design? Maybe it's supposed to be (or is) a TV?

If you have a recommended plug-in...

Use a power window and noise reduction to isolate the banding and leave the rest of the image alone. I was going to suggest using power window and a simple blur but that causes as many problems as it solves as the edges of the frame get funky.

Good Luck

Thank you guys for your comments!
I will try to test and see if its the lighting or something else.
Much obliged

If is light flickering why not test ofx debanding? Work fine and is in resolve studio, I resolved tons of flicking of shooting that I should edit

To add to this: sometimes it may get even better using that filter twice with different settings.
