that problem is that this fish actually appearing after the first tetrapod fossils:Researchers have discovered the fossil of a fish with finger-like digits in its fin that lived 380 million years ago, according to a new study. And they believe it bridges the evolutionary gap between marine and land vertebrates as one of the oldest examples of a skeletal pattern resembling a hand.
The study published Wednesday in the journal Nature.
"Today we announce in the journal Nature our discovery of a complete specimen of a tetrapod-like fish, called Elpistostege, which reveals extraordinary new information about the evolution of the vertebrate hand," said John Long, study author and Strategic Professor in Palaeontology at Flinders University in Australia.
"This is the first time that we have unequivocally discovered fingers locked in a fin with fin-rays in any known fish. The articulating digits in the fin are like the finger bones found in the hands of most animals."
In the phylogenetic tree, this species is near the justly-famous Tiktaalik.

Tetrapod trackways from the early Middle Devonian period of Poland
thus it cant be consider as a "transitional fossil". more than that: we can also find transitional form between designed objects. but of course that it doesnt prove they evolved from each other, even if they were able to reproduce:
