I am using Sydney for little Woocommerce shop. Everything works fine, just one thing is not good
When I import product images to gallery, they are showing blurry under the main image on the page.

Blurry are just the thumbnails, when you click on the image it is showing OK and not blurry. Check the image below:
Can you please help me with this?
Thank you very very much.
