[Therion] Cannot get offset maps to work

[Bill Gee]

Hello everyone - Most of my recent questions to this list have generated 
exactly /dev/null for response.  I hope this one gets something.

I am trying to build a map where one section of underlying passage is 
drawn offset from the main map.  I have done this before and it worked. 
This time therion is completely ignoring the offset parameters.  What am 
I doing wrong?

The portion that I want to offset does get drawn, and it is drawn below 
as I specified.  It just does not get drawn offset.

I tried taking the offset out of the list.  Therion complained about 
that.  I tried offsetting the other two partial maps, and that does not 
work.

The last time I compiled a map with an offset, I was using therion 6.1.8 
on Fedora 38.  Now I have 6.2.1+dev on Fedora 41.  Did something change 
between those two versions that affects how this feature works?

I attached the .th file to this message.

Thanks!
