2 year renewal of AVG Ultimate update only valid 30 days

In July I used the early renewal option for "AVG Ultimate 2015". It was due to expire on 2nd September. The Product has worked flawlessly for many years. Hence my enthusiasm to renew. I also purchased "AVG Secure VPN" (1 yr, 1 machine). After several attempts to install "AVG Secure VPN" I realised I had to uninstall "Ultimate 2015" and then install AVG Ultimate 2017. "AVG Secure VPN" then installed quickly and is working well!
However "Tune-up" and "Internet Security" will both expire in 30 days instead of September 2019.
How can this be corrected?
