Bug: Filter with timestamp using start and end timestamp reveals no results if sorted by NEWEST

[mauho]

We are using AKHQ 0.25.1 with user settings / Topic Data / Sort = NEWEST

The behavior depends on the size of the topic. Working on a topic containing 40GB of data the following applies:
Setting a start AND end timestamp on a topic won't reveal any data. If however start and end timestamp are set, then sorting is switched to OLDEST, the data is fetched as expected.

If only a start timestamp is used results are fetched even on sorting = NEWEST

only start TS   NEWEST   OK  https://address.to/kafka-ui/api/broker-cluster/topic/my-sample-topic/data?sort=NEWEST&partition=All&timestamp=2025-01-06T10%3A25%3A03.000%2B01%3A00
start + end TS  NEWEST   NOK https://address.to/kafka-ui/api/broker-cluster/topic/my-sample-topic/data?sort=NEWEST&partition=All&timestamp=2025-01-06T10%3A25%3A03.000%2B01%3A00&endTimestamp=2025-01-14T10%3A25%3A03.000%2B01%3A00
start + end TS  oldest   OK  https://address.to/kafka-ui/api/broker-cluster/topic/my-sample-topic/data?sort=Oldest&partition=All&timestamp=2025-01-06T10%3A25%3A03.000%2B01%3A00&endTimestamp=2025-01-14T10%3A25%3A03.000%2B01%3A00

The behavior is different on smaller topics. Working on a topic containing 1GB of data, the issue is not present -> start+end time filter works regardless of sorting direction.

Can someone try this on a different system before digging into it any deeper?

Thank you and best Regards
