Word 365 svg import problem

Hello,

When importing svg files in Word 365, subscripts are not in the right place (too far down on the page).

When importing in Libreoffice, it's ok.

With Microsoft Edge, subscripts are ok but some are too far on the right.

With Google Chrome, it's the same as in Word 365.

Any ideas ?

Thanks a lot
