Hey, guys. I have a product that has the following tags

My code for it is like this
{% for tag in product.tags %}
- {{ tag }}
{% endfor %}
Now when I try this code, it’s now showing any product. Even when I change “Lace Up” to “Safety” or “Zip Side”. Why is that? What am I doing wrong?
{% for product in collections.all.products %}
{% if product.tags contains "Lace Up" %}
{{ product.title }}
{% endif %}
{% endfor %}
