The information in the dialog is based on the information that is being logged in both the "server.log" and "impex.log" of the Spotfire Server. If there is any issue and if the information is not being logged to these files then there would be no information shown in the dialog.
First, the current logging level set for the TIBCO Spotfire Server will determine what and how descriptive the information will be in the dialog. Ensure the logging level for the server has not been set to None. This can be set according to the documentation reference
Changing server and node logging levels.
Second, even if the logging level is sufficient, there could be different scenarios why the server could not write to the log files. For example:
1. If the account running the Spotfire Server service does not have access to the "C:\tibco\tss\7.x.0\tomcat\logs" folder then there will be no log entries and you may see below errors in the logs:
2019-07-30 10:22:16,297 localhost-startStop-1 ERROR RollingFileManager (C:\tibco\tss\7.11.0\tomcat\logs/server.log) java.io.FileNotFoundException: C:\tibco\tss\7.11.0\tomcat\logs\server.log (Access is denied) java.io.FileNotFoundException: C:\tibco\tss\7.11.0\tomcat\logs\server.log (Access is denied) ... 2019-07-30 10:22:16,344 localhost-startStop-1 ERROR RollingFileManager (C:\tibco\tss\7.11.0\tomcat\logs/startup.log) java.io.FileNotFoundException: C:\tibco\tss\7.11.0\tomcat\logs\startup.log (Access is denied) java.io.FileNotFoundException: C:\tibco\tss\7.11.0\tomcat\logs\startup.log (Access is denied) ...
2. If any users have opened the log file in any text editor, like Notepad, and if the file is locked by the application then it will not allow the server to write to these log files.
When the account does not have access or for any other reason if the server could not write to the log files then the Library Import/Export dialog will be blank.
To resolve, ensure the logging is enabled and ensure the account running Spotfire Server service has access to the logs folder and the log file(s).
