Did you try using the Full Version? Sometimes the Full Version has much more advantages than the Original Version. Also, are you sure that your using the right country version? Check to see which its set to, either Japan or US.

Depending on what Pokemon you are training, it will level up differently. Considering that your Electivire was on a higher level, it received more Experience while your Level 10 Bagon only received a small amount of Experience. It basically all depends on the Nature and Level of the Pokemon.
