Copperdale world lighting is too dark

I was building a highschool in Copperdale with the Sims 4 High School Years pack and it's a little bit disappointing to see the shadows so dark and coarse. I can barely see the al fresco areas, and it's a shame because the high school I was building has an open layout as it was based on a real school. This type of lighting does not occur in other worlds, only Copperdale. Can I request a fix on this? It really is an eyesore.
