Footnotes are "glued" to text and not at the bottom of the page

[YannickErb]

Hi :)

When using \footnote on pages that are not full with text, the footnote is stuck directly behind the text and not at the bottom of the page.
However, it does not happen to foot notes that reside on pages that are full (e.g., author affiliations on the title page).

I uploaded a blacked version of the project-pdf I am currently working on for submission. Quick help would thus be appreciated.

Kind regards and thanks in advance!

I could not reproduce this yet. However, I have an idea and edited the definition of \footnoterule. @YannickErb, could you please test with this class file and let me know, whether this solves the issue for your concrete example? Thank you.

Thank you for the update on the issue and the edited file.
This seems to fix the issue at first glance!
