Not performed correctly rollover for index.lifecycle.rollover_alias

Question

This is my problem I have configured filebit, logstash to create separate indexes for system and programs But I ran into a problem, the indexes are created, the log separation is fine, the life policy works, but I have a problem that logs are written to the first indexes, then new logs are created according to the life policy, but they are empty, then the first one is deleted and logs are written to it
