Should a non-resident of Canada report income earned under "foreign income" and the same amount under "statement of world income?" in the provincial section?

I am a Canadian living full-time in South Africa, with income from Canadian and South African sources. I entered my South African income as "foreign income" in Turbo Tax, which is about $7000. However, under the provincial section, I am asked again for a "statement of world income." 

Should I write in $7000 again, in the World Income section? It causes my payment amount to increase by $3000 when I do so, and I already pay tax for this income in South Africa, for which I understand a tax treaty exists between the two countries.
