Lumia 630 Calendar Problems

I was entering events on to my Nokia Lumia 630 calendar. All is fine until I get to the 08/04/15 then after I have entered them they just vanish. Be interesting to see if tomorrow the vanishing point goes to 09/04/15! I am linked into google calendar and even though they vanish off the phone calendar they do appear on my online google calendar.

Having same problem with Windows 10 Calendar. Any events created after 1/26/2016 disappear after 3 seconds of creation. All events created before 1/26/2016 show up fine as normal.
