I don’t know what it is but I have to stare at it all day 
There’s a label that says the wood has been treated with copper azole wood preservative but I’m not sure what this stain is, how do I clean it off without damaging it?

I’m no wood expert (well, this kind) but I’d say that’s a fungus growing, possibly some water damage. I would assume that plank got missed for treatment or it wore off over time. So the good news is you don’t need to worry about damaging it, because it’s already damaged. You can try sanding it off and reapplying stain and sealer, but it’s probably rotting inside the wood, so I’d say you’re better off replacing the whole plank.
Edit: I agree with a reply, most likely the copper treatment leaking
This isn’t a fungus, this is the copper treatment, that soaked into the sap hole, bled out and oxidized into the blue green color. It’s because of the wood treatment.
I think that’s what it is, is there an way to remove it or lighten it?
Sand it
Yeah, that makes sense. Like I said I’m no expert. The wood splitting on the right side would indicate other issues with the plank as well, no?
It just got installed by property management, it’s the only problem board and it got unfortunately placed right in front of our window lol
If it’s not yours then fuck it. Sand away, sister.
Hi, just wanted to let you know that i got a report that you quite possibly accidentally misgendered Razgriz. If you could make a quick edit swap from brother to sister at your earliest convenience, I would very much appreciate it.
Your first step then should be complaining to them about how they installed fucked up wood and caused an eye sore. It’s their property, they should fix it
That doesn’t mean they will but it’s worth a shot first over paying for/doing anything to fix it yourself
“What’s the worst I can do, it’s already fucked up” is such a good feeling lol
