TEA5767 outputs wrong radio stations

I'm using a TEA5767 FM radio receiver bought on amazon (https://www.amazon.com/Gikfun-76-108MHZ-TEA5767-Antenna-Arduino/dp/B014QZM53Y). I'm using the following library (https://github.com/mroger/TEA5767) It all seems to work fine, except the radio stations played correspond to some other radio frequency. Has anyone experienced a similar problem?
