Do you have enough consumers representing the number of partitions you
have?  You should have one consumer within a consumer group for each
partition... Think of it as threads, if you have 5 partitions you need 5
threads... if you only have 3 consumers(threads) then it is possible the
data is on one of the other two partitions that has no one reading from it.
