Can't make company transfer building level?

[Strifeboy]

Playing as Spain and wanted to make the Duro company but need to give 5 buildings levels to them. Problem is no matter what I build for it it stays at 3 outa 5, 3 what no idea is has no information on what resources, where to build it, do they need to be private/nationalised. So straight up just confused.

The company builds them not you. 1.8 changes below.

Companies now can own buildings. To establish them you will need to possess some country-owned building levels or pay a lump sum to transfer the levels from existing other owners to the company (depending on the economic law). Once established, a Company HQ building is constructed in a fitting state.

Company HQs can use the investment pool in order to construct new buildings or buy existing building levels. They will prefer to invest locally up to a certain level before spreading their influence.

Company throughput and construction efficiency bonuses now only apply to the levels they own directly or which they are constructing. To compensate for this, these bonuses have been drastically increased.

I think they AI needs to buy up the property first and then give them 1million. Thats how I got it to work.
