Energy balance chart legend label not working

I have a problem about energy balance chart legend labels. Everything seems to work fine with my energy results and no errors and I get the energy balance chart. It is just that the some of the legend labels are showing in the wrong location as you can see in the picture. I do not know why and I tried so many different inputs with legend parameters and nothing changed. I would appreciate your help and direction.
