Hi team,

there is a typo in the italian translation of "Select a maximum of 10 tasks for an action" that is translated with "Selezionare al massimo 10 task per un''azione"; but it should have only one apostrophe not two, so it should be "Selezionare al massimo 10 task per un'azione".

We tried to change it by Sandbox - User Interface Text but it doesn't work. I can select the phrase but when I replace it the interface doesn't change.

How can we correct this translation?

Thanks
