Error: "Your spouse/partner's income for the year is required to properly calculate your tax return...".

My wife had an income of $2500. I filled up all the information in her T4 form, but I continue having this error. When I click the FIX option, it only asks if my wife income was $0 and of course the answer is NO, and it does not give me any other alternative for entering the income in any other place that could be missing it. Because it is an error I can't file.
