Check the JSON of those strike drones. If there is a blueprint in it, remove it. This might be due to you putting a ship name or JSON code in the item defaults (there is a button called Change Item Defaults in Item Mode).
There is a blueprint pre-baked into every strike drone when placed down, for some reason.
I haven't touched the item defaults at all since downloading the world.
Consider removing the item defaults(which may have been left over) in the next update to the world.
(unsure if that's how that works; I might be way in over my head, though fellow newcomers to world creation shouldn't have to deal with this in the first place)

Like what I said earlier, remove the JSON code from the item defaults and just leave it blank (refer to image below). Item or sector defaults that were changed from prior versions are kept in the later versions. That's what it looks like in your case. I tested this on another device using the latest version, and this bug does not exist.
