Upgrade to v 6.0 : Cannot create requirement

Hello,

Since our last upgrade to version 6, an error prevent Spirateam to create new requirements.

The event viewer on the server show the following message :

In APPLICATION.Business.RequirementManager::Insert():

Messages:   An error occurred while executing the command definition. See the inner exception for details. [System.Data.EntityCommandExecutionException]   Cannot insert the value NULL into column 'PERCENT_COMPLETE', table 'SpiraTeam.dbo.TST_REQUIREMENT'; column does not allow nulls. INSERT fails.Cannot insert the value NULL into column 'REQUIREMENT_ID', table 'SpiraTeam.dbo.TST_REQUIREMENT_USER'; column does not allow nulls. INSERT fails.The statement has been terminated.The statement has been terminated. [System.Data.SqlClient.SqlException]

I could modify the DB by hand to make this disappear but I don't think it is a good idea ....

Thanks by advance for help
