Product design and categories

[ELC19]

Hello, I have a couple of ''issues'' at my store. 

• categories
• product text and price not at the same height

Is there a way to remove these categories that automatically show up when I type my product name? I have to manually change each product to ''uncategorized''

And how to fix product name and price to be at the same height for all product? I know that the height changes based on the length of the products name. Is there a way to fix it regardless of the length?

Thanks!

I can't find in the code these css files ''usually named theme.scss.liquid or theme.css.liquid''. When I filter files none of these show up.
