Basic Assembly and Setup

I purchased a Petoi Nymble the cat in Dec 2022 for my son. According to the assembly instructions at docs.Pettoi.com, we should have 5 different screws in the kit. When reading the checklist that came with the kit, it lists only 2 different screw types M2x5 servo screw (12) and M2x6 self talking screws (58). I have also confirmed physically that these are the only screws in the kit. We were able to assemble the head, but when installing the battery pack to the body piece, it requires long screws to allow room for the springs. Unfortunately we do not seem to have these screws. Am I missing somethin? Am I using the incorrect instructions? Any help would be appreciated.
