Matrix visual printing last section twice? (Bug?)

Hi Guys,

Compliments of the new year. 

There something weirds going on in my Matrix in my Power bi report.

What I have done thus far is created a table structure which specifies the rows in my matrixs (Note that each line can/should reflect a different value  for example: Unit price, total cost , profit.)

The value in the matrix is filled with a measure which contains a switch case, resolving different calculations based on the selected row value. (note that it resolves these caculations pretty quickly, and updating the matrixs takes no longer than 1 sec)

Issue that I am facing now is that sometimes it prints the bottom rows twice? And sometimes it does not?

See the first 2 screenshots of March and April, showing the Profit section once.

See the last screenshot of April again, showing the profit section twice.

(This happens randomly which switching between the monthts)

When it happens, the matrix "Freezes" very briefly and I have to make an additional scroll montion inorder to go to the bottom.

So I am leaning towards a performance bug?

Has anyone seen this before? And what could be a good solultion, as my client is not liking this.

Thanks in advance

Jan
