Balena Etcher creating unformatted partitions after "succesful" ISO flash

Hello, I am having an odd error. I select the promox iso and go to flash it to one of my USB drives (sandisk 64GB) and it goes fairly well and even says it completes “successfully”. I am not super well versed on how drives are partitioned and whatnot so bare with me. It seems to create these extra partitions (like ‘I:/’ or ‘H:/’) and just leaves them completely unformatted. I have tried cleaning the usb and reformatting it with diskpart, which while it does make the USB work properly and show up again, the same issue happens when I try to use Balena Etcher on it. I will add a picture to help. Thanks.
