Simscape block configuration change automatically

When I open the copy of a model, I find that the configuration of blocks such as Rigid Transform CHANGE automatically.In the prototype the unit is cm, in the copy the unit is m. Is there any settings affecting all the block configurations?Thanks for help!

I have tried copying the Rigid Transform block from one model to another but the block's configuration is same in both models. I have changed the units to 'cm' and tried again. I haven't been able to reproduce the issue. Could you attach the model?

Indeed this sounds weird. Is there a callback function that may assign units automatically and cause this? A model and steps to reproduce this issue will be helpful.
