No! There is not need to reinstall!
I got this my self, but i knew that was my mistake.
With the "Option File Editor Viewer" (OFEV) (you already have it installed with TWOS: "data\Applications\OptionsFileEditorViewer"), open the "TheDarkWraithUserOptions.py ("data\Scripts\Menu"), go to the "Radio" tab, and disable the option: "Show sub sighted radio messages", save the option file, and that's it!
But this option is disabled by default, I enabled it to see what it does, and that's the effect, exactly as you described. You have enabled it somehow...
Just edit your your option file with OFEV, save, and problem fixed.
Here is a tutorial on how to use OFEV:

(there is an image showing the Radio Tab content, where you can see the culprit option...)
IIRC there is a batch script file in one of the TWOS folders, to reistall the options file for a default one, in case you did'nt made changes to the file, or if you want to start with a fresh one.
Edit: is the "Restore Stock OFEV Settings.bat", located in "Silent Hunter 5\The Wolves of Steel - Documentation"
Good luck!
