Kafka 2.7.2 to 3.5.1 upgrade

Hello,

After upgrading from 2.7.2 to 3.5.1 some topics are missing a partition for
one or two brokers.
The kafka manager shows "Under replicated%" for the topic.
Looking at the topic for some brokers (of 3) partitions are missing (in my
case 1 partition).
A rollback will restore the "Under replicated%" to 0 again (this is the
wanted number).

Is this a bug of kafka or the kafka manager?

Best regards,
Lud Antonie
