book file does not update page numbers
In my .indb book (consisting of 2 documents) the page numbers display as follows:
1-228
1-200
The second unit remains unchanged even after clicking Update Numbering > Update Page & Section Numbers.
Under Layout > Numbering & Section Options, I have these settings:

I have used these settings in many projects before the current one, and so I would expect the above page numbers to change to
1-228
229-428
However, this time this is not the case. I can't find any other setting that may prevent InDesign from updating these numbers. – Anyone an idea?
InDesign 17.4
macOS 12.6.2
