I haven't so much experience in codeforces.There is a confusion i am having about the hit map of solutions in codeforces. I solved approximately 100+ problems in total.But my problem count becomes changed after a few days. After changing it doesn't shows the actual counting of my solution. Could anyone tell me why does this happen?And how can i fix it? There is a picture of my present hit map scenario.But a few days before it was not like this.
