Demand Notice: Challan is not available for the AY. Challan already paid

I have received a demand notice with the following reason "Challan is not available for the AY". I paid Self assessment tax which is showing in 26 AS and also mentioned the challan details while submitting ITR but the same was not picked up during processing. 
I suppose i have to select "demand is not correct" and then "Demand paid and Challan has CIN (With open challan details)". Please confirm. Also, what should i fill in the field highlighted in yellow (refer screenshot attached)
