Point earned by completing a mission assigned to wrong space

Today, I was going through some blogs in Design Studio space. Soon after I commented on a blog, I completed the mission Answer Hero Plus and have been awarded 40 points. Now, the points are assigned to design studio space and I am now in 4th position in top contributors 🤪. I am just a learner in this tool but people can assume that I am an expert if they see myself in the top contributors list. Is it by design or a bug ?
