Records not showing in layer's table

Question

I have a point layer with roughly 2M records. When I open the layer's table, there's no data, but when I select by attribute, the selected records display all the data.

Here's what the table looks when I open it up (kindly forgive me for having to redact it):

And here's what I see when I make a selection:

Why am I not seeing all the records at once? Here's a bit more info:

* I'm using 3.2
* I'm appending data to a "master" layer* I used to be able to see data for the first 400k records
* now I don't see any data unless I make a selection

* when I summarize within, no data is carried over into the polygon layer

Any help is appreciated!

It worked! I created the layer last week and will be adding to it this week and next, bringing the total to around 3M.

Thanks!
