I can only guess that your terminal is in some weird state, and/or your
IFS variable has been set to something bizarre.  The hypothesis about
your terminal being in a weird state is somewhat strengthened by the
mangling that was done in your email.

If you properly quote "$subD" it will avoid any issues with IFS:

for subD in "${array[@]}"; do
  echo "$subD"
done

Apart from the mangled formatting and the missing quotes, there's nothing
wrong with your code.

As for the terminal, you can try running the "reset" command, but in the
most spectacular cases, it's often necessary to close the terminal window
and open a new one (assuming a terminal emulator), or power the terminal
off and back on (assuming a physical ASCII terminal).
