When flash disk ignores write requests and retains old data it is an indication that it has failed and is giving you the last chance to copy your files.
I have run into the same problem a time or two. I've been using wipefs lately to get rid of the filesystem signatures before I do anything else, especially if I installed from the memory stick.
I'm going to have to try gparted next time. Sounds like a solid suggestion.

When a pendrive has been used as an installation image, to return it to normal usage, you need to write a new partition table to it, usually an MBR, (could be a GPT, depending on size), then partition, & add a file system.
