Distinct Count in Stacked Column Gives Error

Hello Community.

I have a stacked column chart as you see in the picture below to show distinct count measures during intervals. Every time I choose a distinct count, the chart gives errors like the left side of the picture. When I got it back to normal count it worked again.  I tried doing it with measures and in the normal way and made the relationship by modeling both directions and still giving the same result.

Could anyone have any solution?

Thanks alot.
Best Wishes.
