Activity "Resume Later" and Calories Count

This issue had been reported by different users previously:

And I've recently experienced it with my Fenix 5S.

When I "pause" my commute ride at 8am and "resume" the same ride at 6pm, the calorie count throughout the workday was significantly higher than days when I "stop" each ride and create two separate recordings. The reason why I prefer the "resume" feature is to avoid too many short recordings. 

I don't know what the underlying issue is, but there could be some kind of inaccurate coding? 

Is this something that can be resolved?
