When the Force Field Projector block is moved while active (with Quark-enhanced pistons, Create contraptions, etc.), the force field blocks it was projecting appear to get 'disconnected', i.e. they become semi-permanent, no longer disappearing if the projector is disabled. If the projector is moved back into its original position and toggled, they will dissappear normally.

Known limitation of the system. Machines from the mod can't really be moved. Which normally would make this a bug but given movement is better supported in Mojang's code it should be implemented. I suspect short term we just need to disable movement. Then long term hook the movement code to collapse the field.

Looks like another user has experienced a related issue. Fields are not collapsing even after the generator is removed.
