This is a known issue with the contract picker. It happens after updating the project management sections in the specification from 2011 to 2016.
If you do not need to change the form of contract in the job, ignore this.
If you need to change the form of contract click Clear all values.
Please note: Clearing all values will remove all of the contract specific project management sections from your specification. This cannot be reversed and should be given due consideration if these have been edited.
Once you have cleared all values click on the form of contracts pull down menu to select another form of contract. This will bring in a new set of project specific project management systems to replace those you have just removed.
