Problem: Lite version says PRO!

Pat. shared this problem 2 years ago

Bought second-hand phone, formatted with total wipe of everything, installed a fresh CM12.1 rom. Now... If I go to the play store and insall RT LITE, I found a RT PRO icon in my drawer! The app manager says PRO version too. The installed Lite version app (from the play store) says RT PRO in the header, but If I go in the play store, the real PRO version isn't installed, while the Lite version is it. The app, however, crashes everytime I try to repeat a benchmark. Never used this app before, just want to try the Lite version. How can I solve? Any idea of the cause of the problem? Thank you
