Hi @CristalViper Are you playing as a Renter or Landlord? If so, there are limitations built into what you can and can't do at different times. Renters have things they can't change. Landlords have things they can't change if the unit is occupied. I'm somewhat going on memory here, but the system IS DEFINITELY complicated. You might want to have a look at the Tutorials in-game.
Landlord, and this was a completely fresh lot, so no one was living there yet. I've mostly figured it out, but like you said, it's really complicated. Shared spaces can't be edited at all unless I turn them into a unit and then back into a shared space. And as mentioned in my original post, I can't remove the last room on the lot. Meaning I can delete anything I build but one room is always unchangeable. Which is why I think this is a bug and not just a complex system.
