Got free missile when trying to remove sub-fleet ordnance

It started when I had a fighter base equipped with a commercial magazine and a hangar deck, but both the magazine and the hangar were completely empty. Then, I prepared a fighter that had an empty missile launcher, but its internal missile magazine was fully loaded with missiles.

I assigned the fighter into a sub-fleet of the fighter base. After that, I ordered the fighter base to “Remove Sub-Fleet Ordnance.” When I advanced the time by 1 day, I noticed that the fighter base’s magazine suddenly jumped straight to 100% capacity, filled with free missiles that shouldn’t have been there.
