Session History API dateFilter not working

Hi please can anybody help me out.
For Kore.AI Session history date filter is not working.

https://{{host}}/api/public/bot/{{BotID}}/getSessions?dateFrom=2019-04-01T13:25:58.515Z&dateTo=2019-05-01T13:25:58.515Z

For whatever date always fetching record of last 7 days. Only and If trying getting record from today to today date then also data or last seven days is fetched.
If not provide date filter then also same last seven days data is fetched.
Check data using limit and skip filter too pls for pagination for me they too are not working.
