I shared my allready existing DB with my Training-DB like in Video #4. Afterwards i deleted all the elements in the DB. But in the Management tool there are still some Analysis visibel. How is this possibel?
There are a few possibilities here. It's rare but it can happen. These are the ones that I know of:
Scenario 2 is the easiest to identify. In PSE, perform an element search (Search > Element Search). If you can find elements and your hierarchy is empty, then those elements are orphaned. You can just delete them in PSE.
Identifying scenario 1 and 3 require running SQL queries against the SQL database. Please call into support if that's the case!
I found the elements via PSE Quicksearch and deleted them. Everything was back to normal :-)
