First night, missing and wrong heart rate, stress etc

This is what my first night looks like, anyone else have this? The current heart rate it shows as of writing this post is also horribly inaccurate, conformed with a chest strap that my actual heart rate is in the high 50's. It was like this last night also but I figured maybe it'd settle down while I slept. Also heart rate has tons of gaps. Either I'm doing something totally wrong or I have to return this malfunctioning item. Thanks.
