Elementary Japanese Daichi 1

I noticed some mistakes and translation errors in the “Elementary Japanese Daichi 1” course. I am currently only repeating older lessons and have to book here to check. First, the first course does not include the vocabulary for “-kara” “where are you from” ect. More importantly Dokusha どくしゃ is translated as “reading”. Depending on the Kanji this is not wrong, but based on the level I assume the translation is supposed to be “single/unmarried”
