Your transcription is correct.
My guess is that the transcribers were concerned that page xix is “skipped.” But it will be accounted for in either the first volume (if there is no brief contents page) OR in the volume in which the page xix content occurs.
For reference, see BF 2.10.12 b. In volumes with only part of the full table of contents, transposed material is listed (with its print page number, if shown) in the order in which it appears in that particular volume.
