Lay My Hat

This is something that is niggling me and I seem unable to resolve it....
I have a bookmarked file which when I delete it by either right clicking my mouse or going into Favourites/Bookmarks on Chrome and deleting it, reappears again when I boot up my laptop the next time
I also know it hasn't been deleted because it doesn't show up in the Waste Basket (is that the right expression in English? Cestino in Italian) which remains obstinately empty.

How can I permanently delete this file? Thanks as always for your help.

Do you have another device which is syncing with Chrome?

Yes, my iphone.

Pambon, are you deleting it from within Bookmark Manager in Chrome? That should delete from all the devices that use the same Google account. If you are and it isn't, then I'm stumped!
