It's a problem where you can't move your mouth when you export it to a json file.
Please understand that I am using the translator because I am not good at English.
My mouth moves well in the Live 2D Cubism Editor. Like a preview of a physical operation, or a random pose.
But when I check the viewer after I send it to the json file, I just close my mouth, but it doesn't work when I open my mouth.
Mouth opening works, but 'mouth deformation' doesn't work.
Did I work on it wrong from the beginning? I wanted to work on it from the beginning, but it was the same.
The same is true of Virtual Studios. Is it an error?
Did I work on something wrong?
Can you tell the cause?

I will send you the working file and the moc3 file, so wouldn't it be faster to check it once?
I wondered if it was the same with other people's computers.
Thank you for your response.
Could you tell me what the settings are for export?
Could you please provide us with a model(cmo3) file for our research?

I sent it. Thank you for your kind cooperation.
Thank you for providing the data.
We have checked the data we received and it works fine.
I used the data you had exported and had no problems.
Could you please check the following
- Check the following pages for hints
https://docs.live2d.com/cubism-editor-manual/fault-map/?locale=ko
- Could you reinstall Cubism Editor?
- Does this problem also occur in older versions (e.g. 4.1.04)?
- Please restart your PC, close all running applications (including those running in the background), and check if the model works properly with only the mouse and keyboard as devices connected to the PC.
We appreciate your cooperation
Thank you.
I tried this and that.
However, they even used the means of formatting the computer, but still the same.
Is there any other way?
Should I send you the log?
@kudo(Staff)
I don't know if I set it up wrong... Can you tell me how to reset the settings?
I have succeeded in reproducing your phenomena.
This is a bug in Cubism Viewer.
The model represents the state of the default parameter values even though I have moved the position of the parameters.
We apologize for the inconvenience.
The model is at your disposal for animation production, tracking, etc. without any problem.
This bug has been shared with the developer and will be remedied in a future update.
We appreciate your cooperation
Thank you.
I also checked that my mouth is working in the V studio.
Thanks to you, we decided to proceed with the work without any problems.
Thank you so much for checking with us for a long time!
Thank you for your hard work!
