In your data directory there should be a .json file for each column family that holds the manifest.
Do any of those indicate that you have a large number of SSTables in L0? This number is also indicated in JMX by the UnLeveledSSTables count for each column family. If not it's possible that the number is coming from SSTable fragments that are the result of a repair/decommission.
