Trouble with manual sleep entries

Hello. 

For about a month I have trouble with manual sleep entries. I do not sleep with watch but every time I synchronise my watch I'm adding manual entries. Watch was recognise when I going to sleep and when I wake up. Now it doesn't, when I "add sleep data" it shows my "static" bed time. Yesterday I changed instinct to instinct solar and today problem still occur. So the problem is with software 16.50 or with garmin connect.

Sorry for my English and thanks in advance for help.
