CCleaner free will not remove ebay cookies

This is odd - CCleaner seems to remove all cookies except for ebay (UK) on Edge browser. I have not chosen to keep the cookies - I've used CCleaner for years and am familiar with how to use it. Seems to only have arisen since I installed the Creators Update and/or latest CCleaner release (5.29.6033) and the consequent upgraded version of Edge. Have tried on 2 pc's with the same results - after a clean I am still signed into ebay on Edge and, having checked within CCleaner for cookies currently on PC, it lists ebay (and no others) as being presen. Any ideas?

Edit - tried using Firefox and it seems to clear them from that ok.
