Block content is duplicating on the front end but looks fine in the back end.

I am working on a site that has an ACF block called a section. It is a simple wrapper with some container html markup and an InnerBlocks element.

I can add an instance of it and inner blocks and all displays correctly. If I add another instance and inner blocks, it looks perfect on the backend. However, when it renders on the front end, the same code from the first instance is rendered twice (same block id, same inner blocks, etc.) If I add additional section blocks, they all show the same inner blocks as the first.
