training effect data sum - bug!!!

I had 2 mtb days.

1 day one (sun) recording and a 5/5 training effect - see picture 

2 day TWO (thu) recordings (one uphill one downhill) 3.3/2,9 uphill  and 1,7/1,1 downhill. If summed: 5/4

When seeing the data on the web or mobile app the daily graph does not sum the two activites. I also susspect that the training load and also the training effect did not summarize correctly the activities (then the 2 seperate activites would make a bigger effect on the correlated data).

thanks
