gINT has three file types (a file set): the gINT project (.gpj), the gINT lIbrary (.glb) and the gINT data template (.gdt).
The file set (gINT library, project, and data template) are designed to work together. If you don't have one of the files that were designed to work together, then you get discrepancies.
The following videos are troubleshooting videos for specific discrepancies that can occur when you are using a set of files that were not designed together, as well as advice on how to solve the issue.
