Thank you for reporting it.
That’s weird but I remember that I have fixed the same issue before.
What is the TOC plugin version?
You can update it with ipm update command.
The ToC plugin is 2.0.4.
I had tried updating to the latest 3.0.0 to see whether it will fix the issue.
However 3.0.0 is not working with app 3.25.4 so I turned back to 2.0.4.
Thanks for the information.
It seems like something is going wrong here.
However I confirmed that it works as expected on v4.0.0b with toc@3.0.0.
I’m currently working on preparing to release v4, so I would like you to wait for it to be released.
Thanks again!
