How can i fix that light behind the couch?

Hello Epic Community. I want to know how can i fix that strange light that shows in the image.(red circles)
Thanks in advance.

What are your lightmass settings? Did you set your lightmass scale to a larger to a lower level below 1 and your IdirectLightQuality to a higher value, like 4?
“The best quality from Lightmass can be achieved with high enough lightmap resolution + Production + IndirectLightingQualiity of 2 or higher (whatever you can bear) and IndirectLightingSmoothness around .7.”

p.s. did my last answer help you? If so, pls mark it as the correct answer. If not, write below the other post what you did to fix your problems!
