list.GroupByFunciton cannot work

[iiiiifinite]

I’m trying to group point by Y axis value .
But it’s not work.
And if group point by z axis value.
It’s can be done.
Have anyone knows why about this?
thanks

If you look at the values you might have differences in the decimals.
I suggest rounding to 2 our 3 decimals before grouping.

But the node does it’s job
