Steps to reproduce:
1. Start Opencast the first time or restart it
2. Open a recording in the Theodul Player
Sometimes some elements of the Theodul Player are missing (i. e. the slidetext tab, the title and recording date of the recording under the timeslider)
All the elements are shown after every (re)start of Opencast
Workaround (if any):
Restart Opencast again (sometimes you have to restart Opencast several times before everything is shown correctly in the Theodul Player).
