When I enter this formula…

IF({Book Type Entry},{Book Type Entry}, “Book”, IF({Book Type Entry},“Advance Reading Copy”,“Advance Reading Copy”))

…the formula field accepts it and all seems well until I go to add more to the formula and see it’s been trimmed down to just this…

IF({Book Type Entry},{Book Type Entry}, “Book”)

…and when I close the customize cell popup I see that the information it was supposed to render for the second part of the formula is also missing.

How can I solve this problem?
