Order under 143(3), penality reg

Sir. amounts deposited during the demonitization period - certain amounts are added back to the income, hence order U/s.143(3). once i received penality notice under section 271AAC(1) read with section 274.As i have preferred the appeals, after payment of 20% of the tax demand, asked the AO to keep the proceedings under abeyance. now i received one more penality notice under section 221(1). How come penality notices under two diferrent sections sir, kindly advice.
