Invalid batch insertion

We used batching a few months back. Since we cannot use lightmapping with batching, we’ve stopped using it. Even though we used removed batching, we used to get warnings of invalid batch insertion. Since they were warnings, we did not take them as important.
But with the recent editor update, those warnings became errors showing like this


Invalid batch 100001 insertion

I’ve checked in the settings, and we have no batch groups. How can we resolve this issue, since it is coming in between during testing the launch page.
Thanks in advance.

It sounds like there are still some models that are referencing a batch that’s been removed in the scene/templates.
