Actually, the support team from Audiothemes helped me solving this issue. Here is their answer:
“It looks like that’s a quirk with the way WordPress works. When displaying automatic excerpts, shortcodes like [cue] are stripped from the content. However, when using a manual excerpt, they aren’t stripped, but they also aren’t processed.
It looks like products in WooCommerce use the manual excerpt field for descriptions, which is why the raw shortcode is showing up in your search results like that.
You might take a look at this article to see if it’ll help you enable shortcodes in your excerpts: https://www.engagewp.com/insert-shortcodes-text-widgets-excerpts/“
Follow the link, it worked for me
