Hide Nested Columns without causing alignment issues

[semsel]

Hello,

We are using a measure for Moving Total of last 12 months Revenue but restrict to last 24 months data always.

To restrict the display 12 months, conditional style is being used, however this causing incorrect alignment of years and months, how to get around this problem.

Not able to filter anything out, as in this case moving-total will be wrong, Please advise if there is another option to achieve other than formatting
