XXA is being used with \c and \v and has the transcription of oral stories. Within XXA I can navigate normally from 1:0 to 1:1, 1:2, etc. but the Interlinearizer shows only the text in 1:0 and will not navigate to any other verse in the chapter. It will navigate to 2:0, 3:0 etc. but not to any verse other than 0. We are using the "manual glossing" option, so it isn't trying to compare with any other text.
I see something in help that says non-canonical books normally don't have chapters and verses. But it also says "Though non-canonical books do not have chapters or verses, for the purpose of having Paratext check the text you enter, you might find it helpful to use USFMs to divide the material into chapters and verses."
As an example of that, running chapter/verse and marker checks on XXA shows no errors. The check is able to find punctuation errors and navigate to the verse where the error is.
I haven't found any documentation that says the Interlinearizer won't work on non-canonical books such as XXA, but I've observed the same behaviour (described above) on two different computers with different projects. The chat bot on support.bible was not aware of the issue and couldn't give help.
