Not temporary at all. B, or actually Gyuki through B, explained that tailed beasts who become friends with their containers simply negotiate a deal with the jinchuriki to take only a portion of said host's chakra in exchange for a portion of said Bijuu's chakra. They still have to shelve their chakra's to use the mode. Kurama was noted multiple times telling Naruto to "use his own chakra" until Kurama could create more Bijuu chakra for him to use. Naruto hasn't used his own chakra (minus the two or three times he was out of Chakra Mode) since this war began, meaning everything he's done since would be removed, since he's technically using Kurama's chakra to preform it.

Tailed Beast Ball is a technique incapable of being preformed by humans, hence why Naruto has to be in Tailed Beast Mode to use it at all, which is, again, not his chakra, but Kurama's.
