time in sleep tracking wrong

i have changed my time zone but still the time is wrong. I went to sleep at 1:07 am and woke up 6:05. When I go to the graph it shows i went to sleep at 6:07 and awoke at 11:05. When I click on the pen in the top right corner it shows I slept for 4:58 hrs sleep...bed time as I stated earlier. anyone else have this happen? How do I adjust? Thank you for the help in advance.
