When copying (Ctrl+C) the chart from the attached source.ods-document and pasting (Ctrl+V) it into a fresh spreadsheet, it ends up like the chart in the also attached destination.ods spreadsheet.

source document with intact chart

destination spreadsheet with broken chart
just noticed - copy&paste works in the same spreadsheet- it is only broken when pasting into a different spreadsheet.
This is flakey behavior. I can confirm that copy pasting works fine in the source.ods.
When pasting into destination or creating a new LO Spreadsheet and pasting the graph is displayed differently.
Not sure why that is, but since I can confirm the behavior: Setting to NEW.
