Hi,
You're welcome! I'm glad it's working properly now.
The issue was related to your caching solution. For some reason, it was still serving an older cached CSS file even after the cache had been cleared or disabled. As a result, two different CSS versions were being loaded simultaneously, causing the background image to be rendered twice.
To resolve this, I removed the collection-saison section class first, which forced the old cached CSS to be discarded. After that, I added the same class back, allowing the system to regenerate a fresh CSS file with the correct styles. This ensured that only the updated CSS was being loaded.
This can sometimes happen when a caching or optimization system retains previously generated CSS assets instead of fully regenerating them after changes. Although clearing the cache usually resolves the issue, some caching layers (such as server-side cache, CDN cache, or CSS optimization plugins) may continue serving stale assets until they are explicitly refreshed or regenerated.
Please let me know if you notice anything else, and I'll be happy to help.
