Font mapping - studio 2019, adding target file font to English and Hebrew

Hi,

I want to set a certain target file fonts as default for English and Hebrew. I go to file type (say Word 2007-2019) > font mapping.

Issue 1) I want to set my default font from Hebrew into English to times new roman, however English is not on the file type list in font mapping. (see screenshot)

Issue 2) when I open the option to select another target file font for Hebrew (in addition to the default Arial) the list opens, but it is "shaded", i.e. not accessible. (see screenshot)

What am I doing wrong?

Thanks!
