"Can't move app to SD card. Insufficient Space." ... But I have 29GB left.

[AC Question]

On my LG G Pad 8.0, I bought a 32GB SD card. It worked fine, I moved all my apps to it until I updated those apps and now I can't move them back to the SD card. The remaining apps on the SD card can be moved back to my tablet but can't be put back on the SD card. I really need a fix because my internal space may fill up very soon.
