Important!
The slug must be unique and must not coincide with the other slugs in the different post types (page, post, casino, game, and bonus) and taxonomies (category, vendor, etc.). Otherwise, the slug will not work.
1) Go to “ACES Gambling” – “Bonuses” – “Slugs.”

2) Add new slugs. Save the changes.
3) Go to “Settings” – “Permalinks” and click the “Save Changes” button. Only after this action, new slugs start work.
