Realtime and baked Lightning

Hello everyone!
Please help me with Lightning.I have a basic VR project for the Android Daydream platform in Unity version 2018.2.17f1

I've added a package with building prefabs made in Unity using Pro-Builder. When I put this prefabs on a scene and then wait until light is generated using standard Mixed Lightning settings I get a terrible light on the models, with dark spots all over the model:

But If I switch to realtime lightning all seems fine:


Could anyone say what is wrong with baked light? (Or probably something wrong with me, so please point me how to fix this to get smooth shadows)
