UE5.3 Blueprint instance changes do not take effect when applied to Blueprint classes, modifying some properties such as the reference system transform, the absolute position changes to a relative position, and the normal prompt is successful, but the changes cannot be applied to the Blueprint class
If you modify other attributes, the prompt indicates that the attributes are not copied, and they will not take effect
Even starting a new project and verifying the integrity of UE5 won’t solve the problem.
Today I uninstalled 5.3, installed 5.5.1 to create a new project and still didn’t solve the problem, and the network couldn’t find the related problems 
, please please help!!! 
I tried again, but it was useless to completely uninstall Unreal and Epic and then reinstall it.
The good news is that only the properties of the model transform cannot be passed back to the Blueprint from the instance, and occasionally the selected instance cannot be passed back from the Blueprint.
I don’t know why, but let’s leave it at that
