NinER fIveR: Well spotted !
In order to extend the Allowable FDP to the extent that it can encompass the proposed schedule times for the route, one suspects that those flights will have to be operated with either 3 or 4 pilots - which FZ already does do on some routes - and which (for a Zagreb) would allow an additional 1:20 minutes with 3 pilots, OR an additional 1:58 with 4 pilots.... wherein the additional pilots will have to take their 'rest' in a Business Class seat (which, with 3 pilots, requires that the adjacent business class seat also blocked-off for use by pax, but that with 4 pilots they can sit side-by-side on another) and, with 3 crew, it necessarily requires that the extra crew member be a Captain (whom is also right-hand-seat qualified).
