Advice on graphs

Hi ,i got my first station up 5 days ago.
Current setup is:
Flightaware blue stick
about 5m of RG6 and a pepsican antenna (design from abcd567 , thank you) which is outside on a plastic pole about 10m AGL
At first i tried to make a coco but the results where poor,about 50nm range.With the pepsican i have peaks to 200nm.On the graphs i have a big number of Tracks with single messages,what would cause this and how to fix it if it can be fixed.
Also any pointers looking at my graphs?

Thank you
