Unusual behaviour in transparency blend modes

I am trying to develop a graphic design scheme wherein the overlapping area of circles on the text changes its colour. I used 'hue' in the transparency blend mode.
However, I'm seeing a peculiar behaviour by illustrator where it's only affecting the last vertical row of the circles even though all the circles have the same appearance. What is happening and how to solve it?
Here's the file.
For some weird reason, illustrator files after getting attached gives this error and I am unable to share the file directly.
