Word count in statistics not updating

I recently copied the folder with my current WIP in it from my D drive on PC to Onedrive so I could work on it on my laptop. This seems to have worked ok.
However, when I check my wordcount on the project/statistics tab, it’s not updating. I just pasted 3 pages of words from another document into it and nada. I’m stuck on 29,423. Help.
