Combo Bar & Line Chart Cannot Change Line Title

Title shows up for Bars but not for Lines. I have tried multiple different metrics too.

Hi,
Im not sure why this issue is occurring but I’m able to see the title for Line for both Combo charts.

I also have this problem

Can you share the chart configurations? like fields added and properties enabled. Not sure if there is some conflict with a particular property
