As I recall, (and I may be wrong) there's a limitation in the underlying librarise that linux uses to format and resize partitions that prevents resizing of FAT32. Try deleting all partitions on the 32GB card and letting the SD card copier partition and format it.
As a last resort, do a clean install of noobs onto the 32GB card then manually copy your changed/created files over.
Note to self: don't feed the trolls
If I've asked you a question, please answer it. I'm unlikely to be able to help without that information.
