I noticed the problem when (1) I deleted the personal cache note on several caches and then (2) visited those cache pages on the website 30 minutes later and noticed that the note was still present.
Thinking I may have done something wrong, I was able to repeat the problem. That was the only reason I did an immediate update to see if the deletion was posted.
After receiving your information, I tested again and waited a few minutes after the deletion and confirmed that the deletion was not posted.
