That is what happens when we get clever and use generic help messages !!
Here is what we can do. In ProfileInfo.controller.php
'description' => sprintf($txt['showGeneric_help'], $txt['show' . $action_title]),
'description' => $txt['show' . $action_title . '_help'] ?? sprintf($txt['showGeneric_help'], strtolower($txt['show' . $action_title])),
This will then look for strings like showPosts_help, showMessages_help, showTopics_help, showAttachments_help and showUnwatched_help and use that (if found). If the string does not exist, then you will get the current behavior (but in lowercase)
