How to submit Bug Fix Question

I submitted a bug fix in develop branch.
I wanted to fix the issue in version-13-beta branch
Do I need to submit this fix in version-13-beta branch also?

This will help you

Thanks. My question is this quotation from the Guidelines.

Note: Fixes to Version 10 will not automatically be merged in Version 11, and so on.

My question is, I contributed the fix to the develop branch. But I need the fix in version-13-beta also. My question is, do I submit the same code fix to version-13-beta branch also?

I think you should submit the fix to version-13-beta as well because if it is merged to v12 and not fixed in beta-13 it means the bug will return when beta-12 goes to production version.
