The rules are in the wrong order.
Consider row 3. B3+365*3 is 10/1/25. Today is 11/x/24. The first format rule returns false. The second returns true and the pink format is applied. Stop if true is set so no more rules are evaluated and you have the wrong color since less than a year to go should be green.
You should not test for < 3 years unless the tests for < 2 years and < 1 year have both failed.
Reverse the four rules. If there is less than a year to go, apply green and stop. If not, then if less than 2 apply orange and stop. ...
Since the last rule applies no format, it can be deleted. If you need to keep it, it can be simplified to TRUE.
