Issues With Importing Drum Music To Braille

Hello, apologies if someone as already asked/answered this. I have a blind student learning drums and bass guitar. I have been able to make bass sheet music very easily for her with musescore (just create a piece of sheet music as I normally do, then save it as a .brf). She has no issue with reading these or embossing them. Unfortunately, when I save drum sheet music as .brf, the files do not properly render. She says that they look like letter notation that she would she for other instruments, not as drum notation she has seen before. Is there anyone that knows another way to properly export drum sheet music as a braille file? I have no issues explaining the rhythms to her in real time or just recording audio for her, but I would like to have the option of giving her sheet music for reference.

Thanks.
