Help matching is on the exact slug

Articles are stored against the product slug and matched as an exact string. Unlike licensing, the help path has no alias resolution, so a product whose plugin calls itself one thing while the hub row says another will never sync.

Read the real slug off the grey chip beside the product name, and make the plugin answer for that exact string. If you must change a slug, rename it on the Products screen so the change cascades into the cached articles and the help settings — renaming any other way orphans everything.
