Windows update cleanup not clearing

I installed the latest cumulative update for Windows 10 2004. When I go to storage to cleanup Windows update cleanup, it cleaned up but not completely. It didn't say 0 bytes like before. I think this is a bug in 2004. I created a test user account but issue didn't get resolved. Last time, I basically reinstall Windows. If I repair install Windows, my Windows update history might be empty. Any ideas? Here is the link to the feedback in the hub; https://aka.ms/AA9yi85. Please help me upvote it. I like more upvotes to get the engineers to take a look at it. I re-created my issue in the feedback.
