fix: double free and double openEditor

I hadn't pulled latest change to main before my last branch-checkout.
There was some old code mixed with new one. Specially, the "note return"
button introduced in last version displaced the openEditor and some
free() inside a loop. That caused duplication of this part of the code.
I should be carefull next time to work on up-to-date branches.
