Repro 6.4+. MSO opens it as LO, wrong. With LO 3.3 it's similarly saved so I set from 3.3. MSO doesn't show it anyhow bu regardless, chart is wrongly saved in LO.
On pc Debian x86-64 with master sources updated today, I could reproduce this. Exporting in odp is ok, when reopening the order is identical to the original pptx. So only impacts pptx export.
