Reproducible: Always

please attach the DOCX file with that formula we can test it

Looks like change tracked deletion of equations.
Such are not really supported yet, see bug 111854 (CT of equation in Writer) and bug 101378 (import of partially changed CT equation from docx).
This one looks like completely deleted equations in docx, somewhat different from the partially deleted ones.

The example file in Word and Writer side by side

Here the entire equation is deleted/added unlike in bug 101378 where only parts of it are changed.

Comment 6 NISZ LibreOffice Team 2021-08-16 10:42:15 UTC

Confirming: change tracking for equations is not supported at all in DOCX import.

Repro with the earlier version on my computer:

Version: 7.1.0.0.alpha1+ (x64)

Repro with the latest version on my computer:

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 2b0b4ddc8bd8fdd4cd689300620fe4621d7533b7
CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: default; VCL: win

Can someone test it with an earlier version of LO to check if there is a regression?
