Daylight values not calculating correctly on two individual grids


I’m trying to generate a daylight analysis on two individual grids, the one being an outdoor area that acts as a floor and a roof and the second lower grid being an internal underground space. However, something appears to be wrong with the generation as the values are extremely low even for peak summer hours.
