Categories not seperating produces

Hi i have an issue where i made product categories but in my shop page when i try to click a category it just shows the entire shop and does not separate what should be in each category.

some example photos below

as you can see when i click a category link is “product-category”

but its showing products not in the category.

Please help with this fix
