Hi @vegaed, you’re not doing anything wrong. There is a known bug related to the updates of the overriden values of component copies that seems to be the cause of the problems you’re facing.
Somehow it seems that if the style changes are made and updated from the object from which the component was created (the “original”), the overriden values are keeped. In the gif below the board “1” was the original component, I’ve created a couple of copies, changed their content and then made some style changes and repositioning inside board 1 before updating it. It looks good but I also could see that text styles are not being properly updated.
We are in the middle of a deep rework of the components system and fortunately it is in a very advance stage. The described issues will be solve with this major update (@jdittrich thank you very much for the offering but a new ticket won’t be needed).
