endnotes on separate pages - ebook

Hi Folks,

I dropped my Word2021 docx with multiple endnotes (insert>endnote in Word) into Calibre (latest ver), converted to epub. I then dropped it into Kindle Previewer and all endnotes are on separate pages. (see 3 images attached),

Two questions:

1) What should I examine, and in which SW, to determine a fix? I'm comfortable with finding and fixing, and adding, small things in css. I'm better in html. Pretty tech savvy just need general steps.

2) Viewing my endnotes in Calibre, why are the numbers huge, and where can I fix please ? I suppose it doesn't matter too much, since Kindle Previewer, displays them correctly, just curious.

Have spent a number of hours googling an answer, and am at the end of my rope here, so hoping for a resolution.

Thanks much!
Cat
