Issue filtering personal collection

When attempting to filter items in my collection that are not in any list, nothing happens. It doesn’t time out or show any error but the”filter" tab that you click on to show results does gray out and can no longer be clicked until another filter is selected.

I’ll attempt a screenshot if that would be helpful.

Edit: just now when I tried a screenshot, it timed out with "Something went wrong Error 502”

I assume you mean this one?

Yes, that filter seems underpowered. We will have to look at it. I managed to run it for your account and you have 109 items not any Lists (it took a long time to run and I can see who it might time out if traffic numbers are high.
