To reproduce, make the following minimal changes to the template:

Rendering the PDF with latexmk using pdflatex, I receive the following output:

I added the gray bars to the screenshot to give some visual reference on the horizontal position. They do not indicate the page boundaries! Notice how the last line on the title page is very close to the page boundaries.

Now, switch the PDF engine to xelatex.

The result is the following broken title page:

Note that decreasing the page or volume number to single digits fixes the issue. It seems like there is some tiny difference in spacing behavior in xelatex that makes this line no longer fit within the boundaries. You can reproduce the same issue with pdflatex by increasing the volume number to 3 digits.

This is strange. I'll look into this.

No worries, we are not blocked by it; we switched to pdflatex. Thank you!
