Hi Joomlart Support Team,
I'm experiencing an issue with the JA Purity IV template on my site, https://gracamaior.com.br/. My GTMetrix and Lighthouse scores are quite low due to the high Cumulative Layout Shift (CLS). 
It seems like the problem might be related to the mod_articles_category module, specifically with the slide-1 layout, as it appears only after all images have fully loaded. Although I manually added width and height attributes to the images, the CLS issue persists.
Could you please help me troubleshoot this problem? Any guidance on how to resolve it would be greatly appreciated!
Thanks in advance for your assistance.
