Italian motor racing official Ivan Capelli has said that he hopes the latest delay over a contract for next year's grand prix at Monza ends soon.
At the historic race in September, a long period of uncertainty apparently ended when Bernie Ecclestone and Monza officials announced a new deal.
However, the F1 supremo said the actual contract had to be signed in the days that followed - but pen was never put to paper, according to Italian newspaper Corriere della Sera.
"Ecclestone is elusive," the newspaper quotes Milan automobile club president Capelli as saying.
"We hope to get out of this impasse as soon as possible."
Notwithstanding the uncertainty, only Canada, Germany and Brazil were given asterisks and provisional status on the 2017 race calendar that was published in late September.
