My page totals are calculating incorrectly for a couple days. Is there a way to reset this or should I fix it manually?

Nov 2: it says I correctly read 154 pages and was on page 323

Nov 4 (Entry 1): I only read to page 369 but it's saying I read 200 pages in that sitting? (it should be 46 pages)

Nov 4 (Entry 2): I only read to page 453 but it's saying I read 284 pages in that sitting? (it should be 84 pages)

Nov 5 (Entry 1): I only read to page 483 but it's saying I read 314 pages in that sitting? (it should be 30 pages)

Nov 5 (Entry 2): it is now tracking correctly based on my previous entry (I read to page 507 and it's showing I read 24 pages)
