I had problems with two references that would not convert to the correct format in-text. I tried all sorts of ways to overcome it; deleting the record and remaking it (a number of times) either by using google scholar to create the record or by inputting the information my self, carefully looking at all the settings - nothing would make the in-text citations work despite a number of hours on these two citations. Since they were very important citations the only way around the problem was to convert to plain and then fix up the problem.
