Hi,
If you need to have the same scale for two differently stacked columns, the solution is not to separate axes. That is the safest solution for adjusting the scale to the measures’ values since the scale is adjusted automatically.
You can first stack all the measures and then remove from the stack some of them:


Now we have a report with a single axis automatically adjusting to different filters.
