[TYPO3-seminars] Date appears in frontend but can't be found in backend?!

[Daniel Rutzen]

Strange problem:

I'm using topics and dates. In the frontend, the plugin lists one 
specific date for a topic, which I can't seem to find in any system folder.

I am really going bonkers here... I checked all system folders, but the 
given date entry is nowhere to be found.

Any ideas how that might happen? Is there a way to list all dates for a 
topic and show me where those are saved (in which system folder)?
