Building Space Planning - Error Message

I have been trying to create a building and add some 'Position components' (in the example a rotating door) however whenever I place an object, I get an error message and then I cannot save my session.

The error message 'Save operation cannot deal with Components'

If I try an exclude this element from the save, there is a knock on effect to the building massing elements, these will also not save.

I'm running 2024x HotFix 0.27

If anyone has any ideas on how to solve this problem, that would be great!
