Hey Paz,
it is quite difficult to tell something meaningful without looking at the admin back-end or at least at the website itself; what I can advise at this point is to check if the links in the “Link URL” fields are alive, i.e. lead to actual pages (in case you’ve changes the permalink structure, you would need to change these URLs as well to match the new permalinks). Also, please make sure that the “Filter” fields contain the slugs of the relevant portfolio tags, not their names.
Sincerely,
Andrew / Satori Studio
