Move Bar moving very slowly after using Garmin Forerunner

Hi,

Using iPhone 6, Apple Watch Sport 42mm & Garmin Forerunner 235.

A few days ago I started using a Garmin Forerunner 235 as my main running watch so I could leave my phone and Apple Watch at home. I turned my Apple Watch to Aeroplane Mode and synced the Garmin to the Garmin Connect app. I turned all the Activity stuff off straight away and solely used it for running. Post run it synced fine and the steps etc appeared on my Health app but not on the activity app as a workout (separate issue).

I turned the Garmin off and turned the Aeroplane Mode off and my Apple Watch synced fine. But since then the Move bar has barely moved.

Ive hard reset the watch and also turned my phone on and off. Checked all the settings for my watch and the Garmin. I've checked the Calorie goal as well.

Any help would be great!
