Underquoted.  Run:

echo [:upper:] [:lower:]

and then

echo "[:upper:]" "[:lower:]"

in the two directories to spot the difference.  (Hint - in one of your
two directories, a shell glob is matching a one-byte file name)

As this is user error and not a bug in tr, I'm marking this bug as
closed, but feel free to add more comments if you still need help
understanding the issue.
