Air Mouse Simplecom RT200 Buttons Issue

I have purchased a Simplecom rt200 Air mouse with keyboard and are having an issue with some of the buttons on it, while most of the buttons do work there are a small handful that dont work such as: SET, SOURCE , TV, BACK , PLAY / PAUSE, STOP , NEXT, PREVIOUS .

I looked into what signals are being received when i press these buttons and there is no signal received, I just want to know if anyone else may have had a similar problem?

Thanks
