Multiple work offsets and Z clearance

[screwhead]

With only G54, on repetitive operations my Z axis clears the work piece .5" and then goes up  when it returns home, providing plenty of clearance between the tool and the workpiece.
I've duplicated this code in order to run the same operations on G55 and G56.
The problem I am having is that when the Z axis is done with G54 operations, it drops down to the work piece zero point and then returns home before moving to G55.
This obviously provides no clearance when the tool is moving. I need the tool to go up and get out of the way when it completes the operations on one workoffset before moving to the other.

Here the code snipped between one work offset and the next one. What should I remove or change.
thanks.

The red high lighted block is the problem area, if you are moving from one fixture to the next you do not need to go back to xyz zero.

Just add the fixture offset to the first move line of the second/third fixture code.
