Need Help with matrix display

Hi All,
I have created a two parameters using the latest feature as per the may 2022 update release, And in visualisation i have created a matrix . 
In both the parameters there are almost 15 values , so that the user can select both the combinations to get the data at different level.
I am facing couple of issues which are as following.
If i Select Geo in first parameter and Region in 2nd parameter then I have to click in Expand all down one level hierarchy to show both the cloumns ,after this selection I fixed the width of all columns , once I change the value in my 1st parameter from Geo to Product then again i have to click on  Expand all down one level hierarchy to show both the columns Product and region and also I have to adjust the width of each column, Again when I return to my previous selection which Geo and region so again my width of columns is changed and also I have to click in again  Expand all down one level hierarchy. 
Apart from this if I select Geo and Geo in both paarameters which can a possiblity from a user point of view then even my  Expand all down one level hierarchy is not working .
Below is the screenshot of how it looks .

Thanks & Regards
