CURRENT_DOC_CHILDREN page provider causing issues with resultsCountLimit = 50

For the new adobe connector we are using @children in the api call to browse the repository (9.10, built using the AWS AMI template, Postgres). This is using the CURRENT_DOC_CHILDREN page provider. We start getting -2 returns once we hit a location with >50 objects (can remove content and it works, add content, it breaks). We are using pagination, so this is not working with -2.

We have tried overriding the default component via the studio project (to modify the resultsCountLimit setting) but it does not work. We can create a custom pp and call that, but that is not ideal. We would like to use our default apis as much as possible. I am attaching the api call that is being used (against a silicon publishing server) and the results.
