Products multiple variants

My query looks like:

select p.id, p.name, vo.value, v.name
from products p
join products_variant_options pvo on pvo.product_id = p.id
join variant_options vo on vo.id = pvo.variant_option_id
join variants v on v.id = vo.variant_id

and return rows like these:

+----+-------------------------------+---------+-----------+
| id | name                          | value   | name      |
+----+-------------------------------+---------+-----------+

As you see, there are duplicates... this is **first problem**. The **second problem** is how to return results just based on color and material (as just one) without size variant? Excepted results:

+----+-------------------------------+
| id | name                          |
+----+-------------------------------+
|  2 | T-shirt red cotton small      |
|  6 | T-shirt red leather medium    |
|  7 | T-shirt blue cotton large     |
| 13 | T-shirt blue leather large    |
| 16 | T-shirt yellow cotton large   |
| 18 | T-shirt yellow leather medium |
+----+-------------------------------+

Values in columns p.name, vo.value and v.name are less important. I need unique ids. I fighting with GROUP BY, GROUP_CONCAT, MAX/MIN, etc... without results... **UPDATED:** Added fiddle: https://www.db-fiddle.com/f/vNL6HWXjjx52cpFeCbR177/0 Question is, how to return products only one variant just like red cotton, red leather, blue cotton, blue leather, yellow cotton and yellow leather without looking at the variant "Sizes".
