TSDB blocks are automatically cleaned up, but it does this on the 2 hour block management schedule. Blocks also must be fully expired (maxTime) before they are deleted.
You probably just need to wait for the maxTime on the oldest block to expire. Look in the meta.json in the TSDB block directories.
