Strange screw used in mounting bracket for Spotlight Battery Cam

Has anyone ordered a Spolight Cam Battery recently? Just got mine and trying to mount it but can’t because the screw used in the mouting collar is so uncommon and i have no bit for it. The screw driver included with the kit is a standard philips but the screw in the mounting collar is star pattern but it also has tiny stem in the center of the star protruding that i can’t use any regular “star” bit. This is so frustrating. How can they use such a strange screw? Now my only option is to drill the thing out and use another screw. I’ve included a photo. In the center is a protruding stem preventing me from using a regular star bit.
