Display reference string chainage in MXROAD dynamic sections

Hi,

Just a quick query with an answer that is no doubt staring me in the face; how do I display the section location in chainage relative to the master string rather than relative to where the sections start using dynamic cross sections?

For example, I'm looking for sections from Ch.1700-1800 on a master string which MXROAD V8i SS4 duly produces. However, in the Dynamic Cross Section Viewer, the chainage given in the drop-down menu at Ch.1700 is 0000, 1710 is 0010 and so on. The sections were taken along a master string and are in the correct geographical location, they're just not labelled correctly. My colleague's machine does display absolute chainage relative to the master string but neither of us know how that came about.  I tried right clicking on the drop down and hunting through the settings but to no avail, any answers out there?

Thanks in advance.
