Why my Gaussian blurs built using spot colors convert to CMYK in Illustrator

[Bill Zablackas]

Gaussian blurs built using spot colors are converting to CMYK. I need it to stay as a spot color. It worked up to the latest upgrade. Whate did Adobe do now?

It is a known bug that has already been reported a couple of times.

Still no fix as of 8-1-2020. It still works staying with older version 2019 Illustrator. I will go that route till its fixed.
