Adding a color to the apex chart series removes the previous months data from monthly utility sensor

Configuration Frontend
1

The set up: I have a monthly utility sensor used to capture energy usage from a smart plug.

So here is the issue I am having, I use apex-charts to plot that monthly usage. And if I use the color option under series, the data from July is not shown.

Let me show you these 2 screenshots: red is with color, orange is no color.

Is this a bug or what to do about it?
