Minister keeps making obsolete ship

Ok, I am using SE 1.66 w/Balance Mod 1.12 and I'm not sure if this is a mod thing or an SE thing in general.

My empire was getting rather large and plus I had recently contacted and made treaties with quite a few aliens with the "colonize each others sytems" proviso. Well, I turned on the Minister for Ships - Colony and Ship building so he could build then control the colony ships. Well, I designed a Carrier afterwards but was going to wait for a few more techs to level up before putting any into production. I kind of figured the Minister might want to try to make some of these as I didn't have any other military ships, just colony ships (yeah yeah I know but I wasn't at war..anyways) so, after I designed it, I obsoleted it so there was nothing but colony ship designs available to make.

The next turn I checked the queues and alot of my planets were making this carrier even though I had obsoleted it. I went through all the queues and deleted them and ran another turn - same thing. I finally had to just turn the Minister for building ships off because he wouldn't stop making this ship.

Is there anything I can do beyond just turning that off? Is it normal for a Minister to make obsolete ships?
