Dropped Grattler on Kahl week 3 mission disappears

[(XBOX)Dead Red Heat]

Once you pick up the Grattler, after the crash, if you drop the Grattler to fight with your machete the Grattler disappears. Two runs, had it happen on both (mashing buttons trying to command Brothers, which is also broken). Double tapped B two swing and it released the Grattler, which only retuned after death. Was no where to be found. Even went back the the beginning where the Grattler appeared to check. Hard to fight the boss with a machete.
