Doctype multiple tab issues

Hi There,

I am trying to add 10 tabs into a doctype, however, after I created 4 tabs in the doctype successfully, the section breaks/column breaks I am trying to add on the 5th tab or 6 tab won’t show up in the form builder. I tried to add them in the fields section of the doctype, I can add them but they won’t show up in the form builder or the actual form.

Is this a bug? Have anyone encountered the problem?

Hi,
I tried and I was able to create 12 tabs without any problem.
Can you attach some recordings?
