Page number intend problem in table of contents

[cabr]

Hi there,

I have a problem in with my table of contents, which I believe must be very easy to fix. However, I am just not able to locate the problem. The problem is as follow:

The page numbers of my Heading 1 sections are intended more (from the right side of the page) than the remaining heading page numbers.

Please also see the screenshot for an illustration of the problem.

I would be very happy for any Tips on what I am missing here!

Thanks, Carolin
