scale master issue

I finished a model and exported it sized to 152mm. When I exported it and opened it in another program the size was correct. Then needed to make a few changes. So I imported the file and made my changes. No changes were made to the size. Now when I export the model, the size in zbrush shows correct but when I open it in another program it is 3x the correct size. How could it be right first then wrong when I make no size changes.

Also as a side question. On my original model I was able to size it to 152mm but now I am only able to size it to 100mm? Not sure why that is happening either.

Thank you in advance.

It is not just scale master that will not size past 100. I have even tried to use geometry and I am having the same issue.
