Hi @raphaelfelix!
So, I’ve been searching for similar cases and found another occurrence of a styling issue with the external component react-slick here in the VTEX community: React Slick. In this topic, it was highlighted that the issue could be worked around by applying global styling inside the element to be styled.
As a side note, I’d like to point out that if react-slick is being used as a complement to the https://developers.vtex.com/docs/guides/vtex-store-components-slider app, it is marked as Deprecated. Because of this, we have a native VTEX app that serves as a slider, the Slider Layout!
Hope this helped!
