Nature of Business code 16009 changed from 44AD to 44ADA from FY 2018-19

I have a photo studio  business with income of 20 to 25%, I have filled ITR for FY 2017-18 in Presumptive income under section 44AD using Nature of Business code 16009-Photography with  income of 20%. Now when I am trying to file the same for FY 2018-19 Nature of Business code 16009 removed from 44AD and added to 44ADA. I don't have income of above 50% as I usally do wedding photography with rental cameras.

Now, how to file ITR for FY 2018-19, If I have to file ITR 3, then I am not maintaining proper books as per accounting standards.

Please help me on this.

Thank you
