Previous step does not mark as past

[nathalystefania]

When I go to the second stage, it marks the first stage as 'past' but when changing to the third stage it does not mark the previous step as 'past'. What will be the problem?

This is my code:
watch: {
moveobjetivo: function(){
let moveobjetivo = this.moveobjetivo
if(this.moveobjetivo === true) {
this.$emit('can-continue', {value: true});
this.$emit('completed-step', {value: true});
} else {
this.$emit('can-continue', {value: false});
}
},
...

Thanks!
