Pressing "Good" on a learning card does not advance it

One specific card of mine is not advancing in interval even though I have marked it as “Good” a couple of times. It is still stuck on a 1 day interval (as evidenced by the fact that I marked it as Good today on 09/30 and it’s still going to try and show it to me tomorrow, 10/01).

This card should have a 3 day interval, but it’s still stuck repeatedly at 1 day. Other cards in the same main deck, and also other cards in the same filtered deck, all don’t seem to have this problem.

What is going on? Thank you!

This can happen if you change learning steps while cards are in learning. Eventually, the card will graduate. Rating it Easy or Again should fix it at once.
