Usually these kind of mistakes are caused by not using a canonical URL as href in the hreflang annotation.

For instance, if the url is www.domain.com/product-a?=color&id="red" and that same URL is canonicalized toward www.domain.com/product-a, but the hreflang suggest has alternate href an URL like this: www.domain.com/en/product-a?=color&id="red" as alternate URL for English speaking users, and this one too been canonicalized to its own non parametered version (www.domain.com/en/product-a), then Google will start telling that it doesn't see any return url... why, because in the canonical URL the href is not www.domain.com/en/product-a?=color&id="red" but www.domain.com/en/product-a.

The same is true in the case of the self referential hreflang annotation: it must be the canonical URL the one in the href element of the hreflang annotation.
