Bar Chart shows same value for different measures and not in Card visual

[MacJasem]

Hi Guys

I've got this bar chart that shows the same value for Realised/Realised YTD (are exactly the same) and Realised/Realised YTD LY (are exactly the same) when the view is drilled up to year level, but different if i drill down to a single year. Take for example 2019 looks like this drilled up:

and this is the drill down into 2019:

How come the Bar chart values if drilled up to year are different from what i see if i drill down to months in the bar chart visual?

Anyone know what is the reason for this?

Thanks in advance!!🙏
