Recycle Bin cleaning not removing files in CCleaner v4.14.4844

Hello,

I have CCleaner v4.14.4844 on (2) Windows 8.1 PC's and CCleaner is not completely removing the files in the Recycle Bin after a clean even though the Recycle Bin on the desktop shows being empty. But when I immediately re-run the program it shows the same amount as before as being removed. I have verified this on both PC's.

What is the problem/fix?

under Options, Advanced, what is the state of the option Only delete files in Recycle Bin older than 24 hours ?
