Effect problem on fix one

Please let me know what I am doing wrong.

Fix 1-8
Place them into a pan FX from the window press set and click sign.
Fx is running and all is well
Save that as pan FX

Then with that running I hit set and turn the FX to off.
FX stops and all is good

Record this to the FX pool for a simple pan off.

Clear programmer.
Call up 1-8.
Run pan FX. All works

Press pan FX stop.
2-8 stop and fixture 1 keeps going.

The only work around is to record the stop on fix 1 as a seltype.
Why is this and what am I doing wrong?
