Maximum amount of attributes?

Hello, we are experiencing some trouble, in woocommerce -> settings -> products filter -> structure i selected about 150 attributes, but when i saved it it only saved the first 85-100 attributes and the ones that came after were unselected. (See screenshot)
It feels like there is a maximum number of attributes. If so, how can we remove this cap?
