Second ITA34 shows I owe SARS the exact same amount they owed me on the first one

I submitted my tax return and first ITA34 showed SARS owed me R7000 but was being audited. I submitted all my supporting documents and now the second ITA34 shows I owe SARS R7000. Why is this? I don't owe them anything right?

This means that they have not accepted something and in fact reversed the amount they originally owed you which has the effect of no one owing anything. Take the original assessment and add it to the second one, the result is zero.
