When you export Printdefinition set with the File Type "X" (XLS) or "L" (XLSX) and you want to import it on any other database, the import fails with the system message that the file type is not supported.
Reproducing the issue
1. Add a new Printdefinition.
2. Go to the Email/Fax tab and choose File Type "X" or "L".
3. Go to coresuite designer → Import/Export and export the new Printdefinition.
4. Go again to coresuite designer → Import/Export and import the xml file saved in step #3.
The following system message appears:
The Printdefinition is imported.
Change the File Type to a supported one, import the Printdefinition, and then change the File Type to X/L where you imported it.
