To have report for a specific time range you can enter time while defining the date filter. Like 1/3/2018 07:00.
For permanent solution you can try maintenance functions to clear and rebuild all work periods. Try it first on a backup to ensure it works fine. While rebuilding work periods enter a start and end time for newly created workperiods. For example if store opens at 7 AM and closes ad 10 PM enter 7 and 22. Or you can enter 6 and 1 to crate work periods that starts at 6 AM and ends at 1 AM on next day. Please keep in mind if there are tickets created out of the configured ranges these tickets will not appear in reports.
