Why is Illustrator changing my CMYK numbers?

Am attempting to print separations for a T-shirt. I will set one object 100% black.

enter image description here

I will change another object to 100% Yellow. Then when I come back to the first object, these are the numbers:

enter image description here

Then I go back to the yellow and 100% yellow has become 3.88% magenta and 93.26% yellow.

As usual these surprises rear their heads when I’m on deadline. Why is Illustrator doing this to me?

Answer

Your document might be set up as RGB. Check that via ‘File → Document Color Mode’ and switch to CMYK if needed. Then update your objects again to use CMYK values.
