Format rule work not correctly

[sayan1]

Hi friends

I have make app for counting my cattle.

I have list of the cows with description, where I am write info about ID of the cattle, gender, age, color and horn.

For best visualisation I want to use rule format for color and horn.

I have 200 cows with 7 different cows. Some cows with horn.

So have make 2 types of format rules.
red cows with horn
AND( [Color]=“red”, [horn]=true)
red cows without horn
AND( [Color]=“red”, [horn]=false)

But my result for two types of cows is same
