Bright corners after baking the light

How can I fix this bright beveled corners problem? It’s only there after building light, I found out that if I turn off the static shadows then this problem dissapears, if I start changing the contact shadow length value it partially dissapears, and also if I change the color of the light to ie red this corners also turn red: Screenshot - ed6b7061b557d7e3728b2c7753db1bc0 - Gyazo
