I can’t reproduce with: Version: 7.5.0.3 (X86_64) / LibreOffice Community Build ID: c21113d003cd3efa8c53188764377a8272d9d6de CPU threads: 6; OS: Mac OS X 12.6.2; UI render: default; VCL: osx Locale: en-EG (en_EG.UTF-8); UI: en-US Calc: threaded You seem to be using Ubuntu builds, I suggest trying the builds from https://www.libreoffice.org/download/download-libreoffice/, if the issue is fixed there, then it is a bug with Ubuntu package (they are using too old version of libharfbuzz).
It's working with the deb package on the LibreOffice website and with the ppa package on Ubuntu 23.04 that has a newer libharfbuzz package. Thanks
