Preset Concerns

In several cues director wanted two MLs poinitng to same spot. To recall positions quickly I set them once and recorded a Preset. Several cues were recorded using the Preset to im and focus the MLs.

Later we wanted to change one cue and ran the MLs down to zero. But then we saw the other cues set with the Preset had also gone to zero! And visa versa - setting Intensity up in one cue caused others to come up? 

It seemde to me that when we changed the INT of a Preset fixture and "Updated" that cue the Update also rewrote & saved the intensity of the actual Preset. I should add we use "Cue Only" mode. 

Is this expected? If so is there  way to deconnect the fixture from the Preset?
