There is an error in the compendium: When you drop a "Ring of Protection" onto a character sheet, it does not set things properly. It correctly adds +1 to the AC but does not add the +1 to saving throws. It looks like the "Mods" field of the ring has: "Item Type: Ring, AC +1". It should read: "Item Type: Ring, AC +1, Saving Throws +1" similarly to the "Cloak of Protection" which does set things correctly.
