Storyline font keeps changing back to standart one

Hello,

Pardon my english it is not my native.

When i am working with layers in a slide and i want to add a text-box to that layer, the font automaticaly pops back from arial to the standart Articulate font.

When i create a text-box in my primary slide/layer it does not do that, and is just an arial font.

I created masterslides with Arial and also on the design tab i selected the Arial font to be primary.

Though it keeps changing the font of textboxes when i create a layer or duplicate an excisting layer

Does anyone have any ideas on this?

Thanks!
