I'll log this as an issue. I think the reason is that there is some older code that is escaping single quotes for SQL server (in inline SQL, singles quotes are used to indicate strings, so if they appear within a string, they need to be escaped by using two single quotes).
You could try a find replace on the language elements in SQL to fix it locally on the imported data.
Something like
UPDATE tblKartrisLanguageElements SET LE_Value = replace(LE_Value,'''''', '''')
