Hi Long,
Thanks so much for the reply. Sorry I'm referring to the Before/After fields in the standard Elementor Dynamic Content popup, not metabox. So when you use any dynamic content in Elementor you go to the Advanced Tab where you can enter Before/After/Fallback.
That's the info that's not displaying properly. It shows when previewing the skin, but not when the skin is used in a group widget. The variable itself loads, just not the Before/After content.
