Need Help With an Old Problem That Has Returned :[WooCommerce] Different Sized P

It’s almost as if my website is behaving like a resistant ‘super-germ’ that has somehow learned how to become resistant to the fix which two members of this forum (superkot and lorro) kindly helped me with a month ago. The resolved thread was entitled ‘Different Sized Pictures On Woocommerce Shop Page,” and although it was, as stated, fixed at that time, the problem has returned…even though the line of code which I placed in the ‘Custom Code’ section is still there.

Here’s a link to that past post, in case anyone might be willing to help me; it might clarify the whole past issue and what was done:

Any help would be appreciated more than you know.
