Yes at the moment there seems to be a bug that isn't allowing the cancellation of fleet builds.
On the top of the build factories you can choose a package size - if you put this to "2" everything will build up 2 times (like in this case).
There was a bug (some weeks ago) where you can only cancel fleet builds when you are in the correct section (so for defense on the defense page and for ships on the weapon factory). Now it should be possible to abort it on any page.

Well if you fixed it. Then tell me why I still can't cancel ship's that are building and I am even in the weapons factory page as well. So I am sorry to say the problem still exsists.
I had the same problem today. I had the problem on my mobile phone and tried everything to cancel some orders in the building queue.
I tried to cancel it in the right section and changed from the mobile version to the desktop version without success.

Testet on my mobile phone and you will see my mistake and why I tried to cancel it 
UserID+Universe+Planet where you tested this.
I can cancel my fleet productions.
I agree .. I had the problem recently in Dark Gate .. There I had two orders in the waiting position and could not cancel the first or the second order .. so I let the unevenly built units go through ..
