Flux + VA issue

Hey guys,
Recently i’ve purchased a new VA monitor (MSI G27C2, which is apparently riddled with issues) and after correcting the colours I’ve found that if I have f.lux turned on, some greys turn into brown.
Two very noticeable greys that turn brown include the fill colour when using Youtube’s dark theme, and shadowed spots in Apex Legends such as inside bushes and in the dimples of rocks. I’ve found that this colour change almost makes dark areas look like they’re glowing.
Is this something innate to VA panels I have to live with or is there something wrong with the panel?
Thanks
