Scatter chart Percentile Name is duplicated

Does anyone know how to fix this problem.

I have the standard Scatter Chart and I am using a 25 Percentile and 75 Percentile line via the Visualizations analyses.

On the DATA LABEL / STYLE, I am using the NAME on the line.

The problem is that it is duplicated. It would do the same if I use just DATA or BOTH.

I can't find any settings that will fix this duplicate display of NAME.

Any ideas? Help is appreciated.

Is it a bug?
