Calories completely wrong

What Activity Class did you select in the User Settings? 

... and also - could you post a screenshot of your HR during that activity, and another one of the screen Calories?

And this is the readout from my hrm showing 702 calories

I wanted to see the Calories screen of Garmin Connect for given day. And you also did not answer what Activity Class you selected in GC User Settings?

Sorry I thought I put it was cycling.

This is calories reading.

There is something completely wrong in the User Settings. Review them again, and make sure that the age, gender, height, weight, and the Activity Class are properly set. Then sync the app with the watch, and verify in the User Settings directly on the watch that all the data matches the ones in the GC profile.

Thank you. I have done all that and updated the device and re-sync’d but no change. I think it’s a problem on the edge 810 rather than connect as can’t see anything wrong on connect. 

Well, if the settings were wrong, and you only corrected them now, it won't have any impact on the past data. Additionally, if you use Edge 810, you should enter the weight of your bike too. Check the Calories tomorrow - the Calories screen must show the Resting Calories (RMR, around 1400 kcal per day for an average female). If it does not, there is still something wrong with your settings. If the Garmin Connect account lacks also some other data, have a look at the Troubleshooting guide for (some) data missing after syncing,

Will do, thanks for response appreciated :)

... the duplicate account (as discussed in the guide) might be indeed your problem too - I see several accounts under your name. They may perhaps belong to another person of the same name, but you better verify it, and follow the recommended steps, anyway:
