Code used to generate the item (test plugin available)

private static void giveitem1() {
    ItemStack item = new ItemStack(Material.STONE, 1);
    ItemMeta meta = item.getItemMeta();
    meta.setLocalizedName("REEEE.WORKK");
    item.setItemMeta(meta);
    number1 = item;
}

Expected result.

{display: {Name: '{"translate":"REEEE.WORKK"}'}}

Meta data result.

{display: {LocName: '{"extra":[{"clickEvent":{"action":"open_url","value":"http://REEEE.WORKK"},"text":"REEEE.WORKK"}],"text":""}'}}

Minecraft client don't recognize the meta data generated from the api and display vanilla name.

note: I inspected meta data by holding the item and execute vanilla command "/data get entity @s SelectedItem.tag"
note2: You can change "REEEE.WORKK" to "gui.recipebook.search_hint" which if the meta data is generated correctly it will display item name as "Search...", anything else is incorrect
