Word count problem (not showing true total count)

Hi, I’m not sure how to reset to my actual total word count.

Here’s what happened: because I didn’t understand what the new Negative word count” switch meant to do, I switched it on.
Meanwhile, after I typed in about 400 words, I started a new chapter. I deleted two false starts in a new chapter. Then, I started on a different chapter and wrote 660 words.
When I checked the word count, it had started on ONE word for the entire writing session, and the total word count was 3 words LESS than the original count I had written down.

So, my question is, how do I reset the entire draft document to show the entire day’s work of 982 words? It’s like I’ve a lost a day’s work of writing that’s not showing up on the word count.
