If you have more than a 1000 unique entries, then that's just the way excel
works. You can only see the first 1000 unique entries using the dropdown.

You can still use a custom filter to show the rows with the other values.

Debra Dalgleish has some work-arounds that you may want to try:

I have filtered a column called Programs. When I open the filter to view the
programs it isn't capturing all of them in the column. I have retyped the
programs that are missing, and still it won't show.

Any ideas or suggestions?

Thanks!
