When converting between « ods » and « fods » formats with the command-line « libreoffice --convert-to <fods|ods> <filename> », the value of the tag « IsValueHighlightingEnabled » is reset to « false ». Probably in other versions too as many updates occur since first time.
Probably not OS dependent
Do you reproduce this with a recent LO version like 7.6.5 or 24.2.1 ? Do you reproduce this with a brand new file or only with specific file? If specific file only, could you attach it? (don't forget to sanitize if if necessary, see https://wiki.documentfoundation.org/QA/Bugzilla/Sanitizing_Files_Before_Submission)
