I'm using Geopak SS4 .878. I'm gathering station addresses at intersections of baselines. The quickest way to do this would be to use Civil Accudraw with Station-Station. I'm not sure where some strange numbers are coming up.
From the screenshots that show the Station-Offset address, you can see that the intersection is at Sta. 209+52.3759 on one chain and 25+07.7297 on another. You can see that when I do Station-Station address, it is apparently correct for the first baseline but is very wrong for the second baseline.
I included another screenshot to confirm that the tick mark is correct. (The other chain isn't annotated.)
