XMind Zen - Copy paste selected from one worksheet tab to another worksheet tab doesn't work!

I was using the trial version of XMind Zen and Copy paste selected from one worksheet tab to another worksheet tab didn't work so I paid $60 and registered thinking that it was simply a disabled feature.

Still doesn't work!  Also there should be a way to create multiple central topics but apparently that is not possible in the full version either.

I'm wondering what besides removed watermarks what extra value and meaningful benefit I'm getting in the paid version???

Thinking now about reversing the charge on my CC if I don't find anything meaningfully different and helpful in the paid version.  Disappointed so far.
