classicthesis roman pagenumbering in frontmatter

i need some help to fix the classicthesis template.
Somehow my Template is not showing the roman numbering on all frontmatter pages. While on the Table of contents the second page is the only page showing the roman numbering. Below is an example of the behavior. I am using this overleaf template https://de.overleaf.com/latex/templates/fra-uas-frankfurt-university-of-applied-sciences-thesis-template/vgjmhzsnwbvj. I want the roman numbering to be shown on all frontmatter pages except for the title page. How can I achieve this?

I am thankful for any help.
