This happened to me as well, on drives where I had written a DVD .iso
image. The DVD image would still mount, even though there was nothing
there, after I repartitioned and reformatted.

I used "wipefs" on the device to clean out the old file system tags.
All of them. Then repartition, reformat, and only the active partition
showed up.

Maybe some experimentation would allow for a "wipefs" command that
only wiped the "macUSBdrive" tags, but I didn't spend that much time
on it.
