Rhythmic slashes in compound time - expected behaviour?

Hi, the music here is in 12/8, I have set options in notation options (or wherever it is) for slash notation to omit the dots. However I have no control over the dots appearing in the bar in which the slash region ends half way. Is this expected behaviour?

Salve, guarda qui e capirai: devi selezionare tutta la misura e poi trascinare.

Buona Musica

It is intentional, for what it’s worth, because the rhythm dots help to make it clear what the total duration of the bar is when the rhythm slashes don’t extend the length of the bar.
