Suggestion: Is there a reason as to why Colorado taxes are the same taken out when there are different specifications on the tax screen?

Hello,

I ran three mock calculations to see if it made a difference what amounts are set on the Colorado tax screen, but it looks like no matter how it is filled out, it always calculates the same. The first time I selected the W-4 form from 2019 or earlier with 0 under the exemption line; the second time I selected Single as the filing status with 1 under the exemptions, and the third time I selected Single under filing status and put 500 under the exemptions amount and all three times it took out the same amount. Can someone explain why this is happening, and if there is a way to fix this?

Thank you!
