We use the clusterize js library to render large tables. This splits the table into clusters of 200 rows, improving performance. If there are more than 200 rows, we hide the "selectall" checkbox, on the assumption that users won't want to select all if there are huge numbers of files, and we can't apply the select-all outside of the 200 row cluster.
However, users can check the first box in a large directory, and then scroll out of the cluster window and select another box. They would reasonably expect these 2 files to be added when they click the "Add files" button, but only the ones within the current 200 row cluster are added.
Here's a workspace with a directory with 400 files in it. I've checked the first file:

And then I've scrolled to the end of the rows and checked the last file:

I click "Add files to request" and only the last file is shown in the modal:

When I scroll back to the top of the rows and click again, only the first file is shown in the modal:
