I have the same issue you do . I haven't been able to successfully restore a backup yet. (And no, I don't compress my backups ) . Also, my backups are on internal SD (since my phone doesn't see my 32gb SD card)
As far as I've seen , there are a lot of people having the same issue we are with all recoveries .

Loving TWRP, but this issue made me change it to Philz ATM.
