# Which Problems Are Solved
It should not be possible to start 2 projections with the same name.
If this happens, it can cause issues with the event store such as events
being skipped/unprocessed and can be very hard/time-consuming to
diagnose.
# How the Problems Are Solved
A check was added to make sure no 2 projections have the same table
Closes https://github.com/zitadel/zitadel/issues/10453
