Sorry, I can’t find the said attachments.
But by guessing, line 521 of the template’s source code appears to be what’s causing the overlapping you mentioned.
Here’s what you can try to fix this:
- Download the necessary template files from GitHub, edit that line to have a higher value, and load these files locally inside Typst web app. Importing would be done accordingly, as opposed to
#import "@preview ..."that you have now. - File an issue on the template’s GitHub, perhaps asking for change of this value, or even that
headingis used, notpar. Apart from making more sense, this would probably also enable you to have something like#show heading: set par(leading: 0.4em)without further altering the template.
