The image shows part of an operation which was trimmed using the graphical editor. The instances of this operation do not have these edits and so are not true instances but I do not know if this is working as designed or not. If I edit anything inside the operation itself, such as cut parameters or feed rate, the instances will update.
Thank you for the clarification, Alexander. I imagine it could be by design since users may want the flexibility to edit some of the instances and not others. If that is the case then a switch would be nice to have.
