Go home always goes via a waypoint in sea!

[Hubbyhatestech]

Can anyone come up with an idea. Hubby ‘goes’ home and it goes via a waypoint in the ocean. He/we’ve never set one. I’ve tried changing home. Removing it but it always does it.
I’ve tried to remove tracking (didn’t work)
It does the timings correctly, distance etc correct, but shows it wrong. Ie it’s just a line from the ocean to home.

Any ideas. Thanks

It's normally to do with poor satellite signal so it has incorrect location data. .

See if you can get a better signal.
