Temp data on Perfect Player

[PeterLang]

I am unsing the amazon fire box with additional SD card because of the low storage option in the amazon box.
So that for i setup the Perfect Player app to the SD card. After y couple of weeks i see some temp data stored on the box ... looks like:

App: 14,48 mb
Data: 1,94 gig
sd card: 21,44

First what i have done is to deactivate countries/ channels i do not see. This moght reduce the data .. but it does not.
Any ideas what that 1,94 gig is? Is it the EPG files?

How can i empty it?
