FireTV 2nd Gen storage

I’m using Tivimate on my fire tv box. Ever since I added it I keep getting messages about storage being out on my fireTV. Even after I have moved every app (that I can) to an SD card, most apps still use a lot of storage on the internal fireTV drive.

Am I using so much storage only from the epg? What other settings of iptv use storage? Is there a way I can make apps store all the info on the SD card? Or anything I might have missed ?

Thanks in advance.
