I am doing indexing for mortality in 1870 Chatham County, NC. Says there are 70 items. Can't get to item 36 and beyond. Only one page showed up
I believe this may help. https://community.familysearch.org/en/discussion/107302/faq-having-batch-submission-problems-or-blank-entries-check-here-first
Most projects today come with a pre-set number of entries. When the pre-set number isn't reached (like 36 out of 70), follow these two steps.
Locate and click on the trash can on your toolbar.
This dialog box will appear. Make sure that you select "All blank entries," then click Delete. You will be left with the entries you have indexed and will be ready to submit your batch.
