Everything is fine. After 4 months (in June), if you will take an international flight with Turkish Airlines (you have it on your account), your status will be extended to a year.
Then there will be another step to change the status for a second year (you have to earn 15 000 miles on flights with Turkish Airlines).
I had the status match in June 2016, flight TK in September, and the validity of the card has changed in October to June 2017.
