Is this just sunburn? If so what should I be doing differently?

Recently moved into an apartment and some of the older leaves on my golden pothos have these spots. If it’s just sunburn, should I do anything differently or just leave them?

There’s lots of new, healthy growth that’s looking great so I’m thinking it’s okay?? I have another pothos (it’s a Jade pothos, hanging to the left in one of the pictures) and it’s doing just fine while being even closer to the windows, so that’s kinda why I’m confused!! I’m somewhat new to the world of indoor plants and haven’t encountered this before, so any help would be appreciated 🙂 thanks!!

p.s., pardon my crowded mess of plants, we’re working with very limited space in this apartment lol
