Adding contract promote an error

[Silverjack]

Working on redmine 3.0.3, when I added a contract, after inputing all the required fields, it shows:

it says begin date, purchase amount , hourly rate , project can't not be empty, I have filled begin date, purchase amount and hourly rate, and I don't have a field called project.

Thanks for letting me know.

Do you have access to the Redmine logs? If so, can you post what the logs say when you try and create the new contract?
