So....I have this doubt. Over the course of the battle against Madara an Kaguya Naruto lost most of hin truth seeking orbs, 3 were use to seal one of Madara's Limbo and other 3 were left in Kaguya's dimension. After the battle with Sasuke Naruto never used the TSO again, it could be that all 9 were lost/destroied or did he lost his Six Paths power? On "The Last" he didn't use it because the film was launched before this power even exsisted in the manga(or anime, I don't know). But on "Gaiden" Naruto used the Toad Sage Mode as if he couldn't use the SPSM anymore, and his Chakra Mode didn't have any TSO nor kept the same style of the SPChakraMode(skin exposed) and the later also apears to happen on "Boruto:The Movie".
