Hi johnny,

Don't change status yourself until somebody confirms, the risk is that nobody read your report.
Can you also provide the file where you found this behavior?

Thank you,

Jacques

Opening the ODF archive of attachment 131314 [details], the last OLE sm formula Object30 has no MathML--so it is correctly blank when this document is opened, so it is not a duplicate of bug 99476

Unfortunately, we do not know why the formulas MathML was dropped and when: (1) during edit, (2) on save, (3) on clean up of the document for posting to this issue.  Suspect it is during edit "moved too much after they are created" is suspicious.

We will need better STR or a reproducing document.

Sometimes they disappear after the edition of a new formula or when you rearrange your text by moving some part of it with for example Copy / Paste.
