Formatting Categories

Hi,

I'm having a weird issue with formatting a category label. With one value onthe Y-Axis the categories format stacked text which is what i want. but with a different value showing the same type of data which it's formatting diagnol and won't format stacked unless i make the chart really wide. But then in a different BI file i have the same chats formatting correctly and its a smaller page layout:

1 - Using SUM Potential GP shown as % it formats like this, but i want it to format the same as the left chart.

2. Using the the different categories but using the same Y-AXIS value as the left chart it formats correctly, but the its showing the wrong accounts:

3 - an old version of this dashboard using the same fields i want to use in both charts formats correctly. but the page layout is smaller just standard 16:9 where as the new dashboard i'm building each page is 1920 x 1080, the only difference on this is that the the 7 axis is a measure calculation that is doing the same as display a % of grand total option:

Any ideas whats going on?
