Why does my modified Ansur test template .mtt file fail to save in the Ansur Test Library?

When you modify a .mtt file (test template) or .mts file (test sequence) be sure to save it as a new version. Include in the Comments field the changes made in this version of the file. This requirement is there for your benefit and serves as a version-control function. If a Save action is attempted without incrementing the version, the file will not be saved, even though it appears to have been.
