So I just noticed Bambu Studio no longer recognises different build-plate designations setup with projects that have multiple plates.
In my project I had set this build plate I sliced to texture plate (you can see in my image).
However when sending to the printer it still wants to select the Tac plate, which is not in the printer. Even if it was, I chose the build plate as texture and this worked with previous versions of bambu studio.
