Chart - Category Label Disappears if the 1st Category not chosen

Hi,

I have a chart that I need to select and deselect certain categories on, however when I deselect the 1st category, the last category label disappears. The data values are there just not the label.

Example:

Mar-18 -through Mar-19

If I deselect Mar-18, then Mar-19 Label disappears. I'm attaching pics.

Any suggestions??

Thanks!
