Duplicate Content on a page that isn't duplicate?

[YYSeanBrady]

So, I've been working on a site for a while, and they recently had one of their blog posts marked as "duplicate content" on Moz Pro:

https://ashlandbreastpumps.com/blog/breast-milk-storage-guidelines/

Reviewing this post, there's nothing here to suggest that it should be considered duplicate. Link is marked canonical, there are no weird domain shenanigans to cause confusion, the content is distinct, and there's a lot of content there that prevents it from being overcome by coding white noise (So "more content" wouldn't be a solution here). So I'm trying to figure out why this particular post was flagged. Did Moz Pro make a mistake?

You could hit mark as fixed if you believe this is a non issue really.

Except Moz doesn't explain how it's duplicate. The post itself, when compared to other pages, looks quite different. There's a canonical tag in the section. There's over 2000 words in this particular page, which should rule out the "not enough content" issue that sometimes happens with these. Finally, there are no weird (sub)domain issues that could be a cause, since it's on the primary domain.

The lack of an explanation as to what's causing them to raise this flag is at issue here, especially when it shouldn't be raising it.

It does not. All it says is that there is a Duplicate Content issue without specifying what is duplicate about it. See screencap.

it would have been marked duplicate if the content is 70% similar to other pages on site. I have seen this being reported for my site as well.

It should list which part or text is duplicate and from where.
