Carlson Survey, Distance offset issues

Anyone else noticing an offset issue with Carlson?

I find that it's doubling the offset distance that's recorded.?ÿ Weird that in the rw5 the distance is correct, but when I run the file, the offset is added again.

If I delete the offset notes, and run it again, everything comes in correctly.

--OF,AR43.2437,ZE89.4601,SD149.745
--OF,HD9.0,--Horizontal Distance Offset
SS,OP1,FP1164,AR43.2437,ZE89.4649,SD158.745,--CLF COR

Leaving the notes in causes the distance to be 167.7', which is 18', not 9' away from the actual shot taken.

But if I take out the two notes, it comes in fine.
