Trouble with Mining Starbases

I finally got a some free time to try out Twilight of the Arnor, but I'm having an issue.  I'm playing custom race with the Terran tech tree and super hive. 

I'm having a problem with mining starbases.  After I research all the manufacturing techs, all the mining upgrades should be available, right?  At least that's how it always was in DA.  However, I can only add the first one and then the rest do not appear in the "choose a module to build" window.  Is there some new prerequisite tech I need or is there some sort of bug. 

Thanks.

Indeed, some prerequisites techs have changed. Can't remember them all, only played Yor tech tree.

You need Xeno Engineering for the first mining upgrade, then the rest are from the factory branch.

Some rases can not build up starbases as far as others can, or as much as they could in DA. I'm not sure if the Terrans are one of these but this could be why you don't see all of the upgrades.

I wouldn't have thought some races would not be able to fully upgrade mining starbases. I suppose it makes sense for races that do not have access to the required manufacturing techs, but playing with custom race and the Terran tech tree does provide all of them. Yet, they are not available after perfecting the required techs.
