Helix lists are limited to 28k indicators

Hi! I got a problem, and it doesn’t look like expected behavior. I have a Helix list with ~ 43k indicators, but Helix API /helix/id//api/v3/lists/{parent_lookup_list}/items/ shows that there are only 28k indicators.
API /helix/id/
/api/v3/lists/{id} works correctly and also shows 43k
API /helix/id/_/api/v3/lists/{parent_lookup_list}/items/ deletes only 28k from the list with 43k indicators

Hey there! I wanted to let you know that I reached out to our Helix team with this question, but haven’t been able to get an answer just yet.

This is a bug. We have engineering reviewing this to determine why this occurred and next steps. It would be helpful to understand more about the use case - I am happy to have a direct conversation around this. Feel free to reach out to me directly and we can set up a discussion around this.
