Ref: https://ask.libreoffice.org/en/question/312243/when-outline-mode-get-turned-on-writer/ Even when experimental mode is off, the "Outline mode" caption is present under Options->Writer->View (even though no selectable checkbox is present under it). It should be hidden along with the checkbox.
I confirm it with Version: 7.1.4.1 (x64) / LibreOffice Community Build ID: f67b1ddedeb24fca1c5938e7cebfab73d708b35b CPU threads: 4; OS: Windows 10.0 Build 19043; UI render: Skia/Raster; VCL: win Locale: de-DE (de_DE); UI: en-GB Calc: CL
This was corrected in the patch that added the option to treat sub outline levels as content. It is in version 7.2 release. https://gerrit.libreoffice.org/c/core/+/107815
Verified with Version: 7.3.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 949658028e722e5d2657b503eb20e16e41dbd8cf CPU threads: 4; OS: Windows 10.0 Build 19043; UI render: Skia/Raster; VCL: win Locale: de-DE (de_DE); UI: en-GB Calc: CL Jim, thanks for fixing it!
