Rhino didn't save the condition of layer On/Off?

Hello.
I found that some layer on/off status didn’t save. In this short video i try to hidden some hatches that messed up the view, those hatches are assigned with individual layers. I turned off the related layers and saved. Next step I reopen the file and the layer ON again. Is it bug?

Hi -

Please upload a small file that we can use to troubleshoot this issue. Also, please provide the output of the Rhino SystemInfo command.
-wim

Many thanks.
“MAIN” is the main file, "Upper body " is the linked block in “MAIN”, “Hatch1” is the linked block in “Upper body”

Thanks.
For layer states of block objects to be saved between sessions, the blocks either have to be Embedded or Embedded and Linked. The blocks in this file are Linked only. Saving layer states of such linked blocks would mess up any other file that links the block.
-wim

Thanks for reply.
Then I have to study about Embedded option, I am not quite familar with that.
I think embedded options are larger files.
