Issue found both in TMO 2.5 and TMO 2.7.
You can see it appears to be a summary of all Japanese shipping sunk that day and received at 1730. It's not clear that these are supposed to be communications from the boats themselves or whether these are routine messages from base. Actually they are simply products of Ducimus attempting to give you, as player of the game, historical context for your actions. Surely, sub commanders' names would not be actually included in wartime traffic. Even submarine names or hull numbers were not included in such messages. Trout's radio ID, for instance, was
NAN - ABLE - XRAY - CHARLIE.
Since all these messages go out at 1730 most probably they are routine messages from base and the captains' names are there for historical information only. It would be impossible to receive boat to boat communications from a very long range anyway.
At any rate, you can substitute a message offering you Disney World tickets from Mickey Mouse if you want, or a "please don't hurt me" message from Mr. Tojo.
In any event, if something like this destroys your enjoyment of a mod you have greater problems than Ducimus could solve. No modder is going to do extensive research of every sinking in the war, whether it was reported by the responsible submarine at the time, time of incident, etc.
The water is warm. Jump in and make a perfect mod!
