Case study Error with Form11

I am getting this error below when trying to fill out the Income Form 11, never had this issue before has anyone come across this issue, cheers

You have entered details for an employment/pension in the year. Income must be provided for each employment. (Spouse/Civil Partner)

It may be because you entered a, next employment, unintentionally. You should be able to "clear page" at the bottom and start again.

Went through this for 2hours on Friday! Keep entering data until the bottom of the page. It may clear then.
