convert ODT with multiples svg to epub double the images

hello all,

on linux with LOv5

I create an empty document in LibreOffice.

I create with inkscape 2 images that I save as svg

I import in my LibreOffice document the 2 svg, then save it in odt format

I insert the odt in calibre library then convert it to epub

my svg images end up been doubled and each on top of the other

like if the svg format is converted to another format but both format are still here

any idea how I could solve this issue ?

thx
