It's simply an artifact of your book being very small and the last file being only a single page. When displaying the start of a file the viewer considers the progress to be 0%. Since that file is 6% of the total the total progress is 94%. This is not normally a problem because for a typical book, one screenful of progress is less than 1% and/or the last file is more than one page long.
Since for a single page file *both* start and end are present on screen it is ambiguous which one should be used as the progress.
I can change the algorithm to special case files that render in a single page to report the progress at the start as 100% instead of 0%. That will fix your issue.
