Doing a cursory review of this app, it looks like it uses macros to define the indexes Splunk will search for the Jenkins data. You may need to adjust these values to match the indexes where you've sent the data to. You can adjust the values under settings --> advanced search --> search macros. Look at the leftmost column Name for the following entries.
[jenkins_statistics_index]
definition = index="jenkins_statistics"
[jenkins_console_index]
definition = index="jenkins_console"
[jenkins_index]
definition = index="jenkins"
