Logs are not displayed on the dashboard

[ghost]

Hello!
Logs are not displayed on the dashboard, but the data is stored in database and if I make query via clickhouse-client - logs return.
This is reproduced when different time ranges (i.g. now/1/3/6/12 hours) is choosen, although sometimes 2-3 records is showed.

It works correctly when time range is 24 hours or specific range, such as 17.05.2019 12:21 to 17.05.2019 16:21, but it doesn't work if time range is 17.05.2019 12:21 to 17.05.2019 15:21 -__-

There are not errors in clickhouse & backend service, Loghouse doesn't hang/crash.
