I have been finding a solution for this for so long as I changed themes which wasn't compatible with the woo align plugin, so I'm gonna share it so no one else suffers like I did😭.
Put this in the custom css
.woo-height {
margin-bottom: .75rem;
margin-top: 0;
display: flex;
flex-direction: column;
height: 100%;
justify-content: space-between;
}
