Legacy metric event though EF2

Hi team,

We noticed the following in the Kafka version in use (2.5).
In Dynatrace, the metric is displayed as:
legacy.kafka.kafka.network.RequestMetrics.RequestsPerSec.FetchConsumer.OneMinuteRate.request
However, in the extension documentation, it appears as:
kafka.network.RequestMetrics.RequestsPerSec.FetchConsumer.OneMinuteRate
Could this difference be related to the deprecated Kafka version, or is there another reason why Dynatrace is reporting the metric with the legacy.kafka prefix and the additional .request suffix?

They are using EF2 and the only available metric is the legacy one.

They also don't seem to have any custom EF1 JMX metrics.

Thanks in advance!
