Unable to change text font after update to 1.2

Hi,
I really love this theme but I am facing some problems after the update to 1.2.
First of all, all the text settings I made before the update disappeared: now the font is the same everywhere (site title, post title, body, etc) and to change the settings again does not work.
I am not using child theme and I didn’t change the style.css.
Moreover, I see squares or arrows (depending on the browser) near the menu items containing sub-items. I tried the different solutions reported in this forum (e.g., to force a refresh or to reach the page from the domain where WordPress is configured, etc) but nothing changed.
Please, could you help me with these issues?
Thank you in advance!
