In my servers output log the seeds get listed, I just checked. Maybe it is empty for your worlds because you didn't set a seed but left that space empty.AppData\Roaming\7DaysToDie\GeneratedWorlds\
then open the folder for the world and look for the GenerationInfo.txt. That contains the map seed.
The seed doesn't populate in the output log. It always shows as blank in mine. It also doesn't show the correct world size, always says that it's an 8k map when I almost always play on 4k maps.
