Capture One Live usability for large collections

I'm trying to rate a large collection (about 4000 images) with Capture One Live and have two issues:

1. While the collection was uploading, C1 Live updated automatically and showed hundreds or thousands of pictures in the browser without difficulty. However the next day it only shows a handful (28 on my screen) and I have to press Load More repeatedly.

2. If I filter, for example 5 stars, I'd expect to see the first 28 pictures that are 5-star. However only 3 appear. Next time I hit Load More, nothing. Next time, 1 image is added. It seems to select the next 28 from the total, then apply the filter so only 1-2 pictures get loaded.

C1 Live should have some way of loading thousands of images easily, and if that's hard for technical reasons I should at least be able to see a couple of hundred images that pass a filter with one click.
