Dear Didier,
I encountered an issue with wrong positions of elements when using multiple field maps and SUPERPOSE_MAP.
The problem is shown in the example below.
In the attached example, a dipole is followed by three quadrupoles defined by field maps.
The first two field maps overlap and I am using the SUPERPOSE_MAP command.
The third field map is further downstream following a drift space and normally SUPERPOSE_MAP is not necessary.
However, in the synoptic the X position of the third field map is shifted upstream (attached).
The S position is not affected by this problem and neither are the positions of the elements in the envelopes plot (attached).
Below is the table from the synoptic and the problem is visible in the X position of the Q3 element.

Could you check what could be the reason for this issue, please?
Thank you in advance.
Best regards,
Emil

Dear Emil,
Indeed, It's now fixed
