I expect that this has been reported already, but I could not find any related reports other than viewtopic.php?p=651073&hilit=copy+rocket+silo#p651073 but it does seem to be a slightly different issue.
What did I do? Used Shift+RMB to copy rocket silo settings then Shift+LMB to copy to another silo
What happened/what would I expect?
It did not pass the setting `Automatic requests from space platforms` onto the second silo. This is the case for both ghost and actually placed silos.
I would expect this setting to be copied, especially because copying the full silo does keep the setting.
Potentially not directly related to this issue, but the author of Cerys has commented that custom settings for mods have similar issues (Cerys 1.3.14 at the time of this report), which has led to issues with making circuit controlled charging rods copy settings between each other in a way that appears to be very similar to that of the rocket silos in vanilla Factorio.

I cannot reproduce this, everything works just fine in 2.0.32 and in 2.0.41.
