Your structured-data publisher logo is a PayPal logo. Every page tells Google your brand mark is "Paypal-Logo.png".
What I saw. The /british-wool-stockists About page emits an AboutPage Schema.org block, and inside it the publisher.logo.url field points at /wp-content/uploads/2021/04/Paypal-Logo.png. That image is the PayPal payment-method logo Yoast picked up from the WooCommerce upload library. Google reads it as the Atlantic Shore brand mark. Run the live URL through Google's Rich Results test and the brand-image preview is the PayPal stripe.
What the rebuild does. On the rebuild the JSON-LD declares the real Atlantic Shore wordmark as the Organization.logo, includes a ClothingStore (plus Store + LocalBusiness) block with the full address, phone, opening hours and 1984 foundingDate, and lists Steve Lugg and Sian Lugg as named Person founders. Rich Results test goes from one yellow warning to zero.
