Easy& good interval keep showing 2 or 3 days interval in studying a head limit custom study deck


I created a custom study schedule to some random cards to see what is the effect of my settings on different cards when I hit different buttons (easy, good, hard), after few times of rebuild the custom deck all the cards keep showing me (2 days for easy, 2 for good,) even if i hit easy and rebuild the custome study
it keeps showing 2 days for easy even though it show that i review this card 16 times but it also keep 2 days for easy
Those are my settings:
