Even calendar error

hopefully this is right part of forum. if not moderators please move it to proper one.

i have just started to arrange couple of event for following year and when i wanted to enter them into calendar i have noticed that year 2014 is completely missing in event calendar. 2015 is present but 2016 is missing again while 2017 is there.

is this just bug on my end?
do you see the same error guys?
could this be fixed if it's an error?
there is no rush but i believe that in 2 months this will become urgent issue
