Strange custom fields after PODS pod added

Hi,
I’ve installed PODS and added a simple 1 field custom post type. When I insert a heading and then go to dynamically pull in the text from this one field, I am seeing many PODS internal fields in the list of available custom fields, for example Rest Enable, Storage, Show UI, Sister ID. There are 21 in total. Is this a Bricks bug or have I missed a setting somewhere in PODS to hide these?
Thanks.
