I'm sure someone has brought it up already, but since you said you'd rather have plenty of the same reports than none at all:
When constructing new ships, they are named in a different way than the units already in the game. Eg, when starting the '36 scenario, I do have a light cruiser KMS Emden. If I order another few light cruisers, they have the same names as the other ships (Königsberg, Emden etc), just without the KMS prefix. In the end, I do have a KMS Emden and a Emden... Thinking about it, I'm pretty sure the Kriegsmarine did not use the prefix KMS (or any other generic prefix for that matter) for her naval assets. If you want to use an abbreviation, it would need to be KM (Kriegsmarine) as opposed to KMS. The latter could possibly mean Kriegsmarine Schiff (Schiff = ship) but it would be an awkward construction for a native speaker. A German would rather say "Schiff der Kriegsmarine" (ship of the Kriegsmarine), similar to the English expression "ship of the line" rather than "Royal Navy Ship" which btw is also abbreviated as RN instead of RNS.
I'm still looking into the different starting scenarios, I think the initial IC needs to be tweaked a little upwards (ie: can you build and research all the stuff you have in '38 when starting in'39) but I'll come back on this later.
Still, a great DLC. Frankly, the first one for any game I bought and which I am perfectly happy about. Thanks for your efforts.
