Ties direction problem

Hi Steinberg Community, I’m trying to change the direction of these ties from the view section, but it changes only the direction of the first tie. How can I change the direction of all the ties? Thank you, Valerio Schermata 2020-12-23 alle 17.10.48.pdf (22.2 KB)

You need to be in Engrave mode in order to select the ties separately, then hit F to flip them.
