In my current game (Nullius Mod, using the Transport Drone Compat mod with it), I have gotten the two first Transport Drone techs. I can build most of the Drone Depots and the three modules (Road Reader, Depot Reader & Writer). The Last two Depots, Active & Storage Depots, are not available, by tech, with a much later tech.

BUT, those last two can still be set to be build in an assembler, at this time... BUT, not all of the ingredients for those two builds, which won't be available to be built until that same later tech.

Shouldn't they not be able to even be set to be built until that later tech as well??
