If your family size changed during or since those 3 years, it could affect the amount of income you need for each of the 3 years. IRCC may also calculate a different family size for specific years based on the detailed family information you provide in your sponsorship application.
Did you received an portal email?
Do you meet the income requirements? Assuming you meet the income requirements for all three year, just re-submit your CRA NOAs for those three years to prove you meet the income requirements. That's all that is needed.
Here is the income requirement that I based for family of 6.
If your application to be a sponsor in the family Class was rejected ,you can make an appeal to the immigration to the Immigration Appeal division of the immigration and Refugee Board (IRB). You will need a copy of the refusal Letter.
Did you not check that you meet the income requirement before applying? You were required to verify that you met the income requirement when submitting your NOI. You are also required to continue meeting LICO throughout the sponsorship process. As someone has already pointed out your application is being denied because you don’t meet LICO. If your NOA does show that you meet LICO you need to contact IRCC. You can try to appeal but if you don’t meet LICO most are denied.
