com.linkedin.cruisecontrol.exception.NotEnoughValidWindowsException: There are only 0 valid windows

Hi team, I kept getting this issue when trying to remove brokers/cluster rebalancing:

ERROR: Error processing POST request '/remove_broker' due to: 'com.linkedin.kafka.cruisecontrol.exception.KafkaCruiseControlException: com.linkedin.cruisecontrol.exception.NotEnoughValidWindowsException: There are only 0 valid windows when aggregating in range [-1, 1691979626397] for aggregation options (minValidEntityRatio=0.95, minValidEntityGroupRatio=0.00, minValidWindows=1, numEntitiesToInclude=661, granularity=ENTITY)'.

This is the logs that I found for debugging:

Does anyone has similar issue when trying to remove brokers? Thank you
