Lab 2a

I have an error for Checkpoint 2 that says "Looks like there's something wrong with the filter that should be applied to the Seeing Triple listview to make it show only the "Spray & Pray" records (Steps 40-44). If you want to fix this and re-grade" and I followed the steps to fix it but the error remained and I do not know what I did wrong. I had to delete some data after Checkpoint2 so that the Spray & Pray would only show one date because that is what it said in the steps, but that altered the meetings and doesnt display what it originally did in Checkpoint 2 but now I cant add a similar meeting and dont know what to do to fix the error. Can anyone help me or tell me what to do?
