Hi,

Thanks for attaching the markdown file, that makes this much easier!

I see several duplicate headings in the attached file:

• ->For X:<-
• ->For Y:<-
• ->Gravitational Force<-
• ->Equation of Motion<-
• ->Wavelength<-
• ->Power<-

These all appear twice, but they are under different parent headings.

If you don’t want to use the rule at all, you can disable it with:

"no-duplicate-header": false

in the “Markdown formatting rules” in “Preferences -> Advanced”.

If instead, you want to treat headings as unique if they’re under different parent headings (so that you can have Change in Position -> For X: is not the same as Final Velocity -> For X:, you can enable the allow_different_nesting parameter for the no-duplicate-header option instead:

"no-duplicate-header": {
  "allow_different_nesting": true
}

Hope that helps!
