I think this is actually very unlikely, flatpak is most likely using some TCP based protocol and TCP would take care of this transparently, flatpak wouldn’t know if any packets had to be retransmitted.
But it’s unlikely those would look like this. Flatpak would only see packets in series, so the only effect a failure could have would be the need for resuming the download - at worst you could receive a couple of bytes again due to alignment, but not this much.
This sounds the most likely, most apps just hide retries, flatpak shows exact data transfered.

It uses HTTP, failures can happen at the HTTP layer.
