Automatic summary page number alignment

Hello everyone,

I have an annoying issue with an automatic table of contents in Word: I'm desperately trying to align the page numbers with one digit with those that have two digits.
To be clearer, my document is over 25 pages long.
In my table of contents, the page numbers appear as follows:

1- Title 1 ..................1
1-2- Title 2 ...........2
1-3- Title 2 ...........8
2- Title 1 ..................10

I would like them to appear like this

1- Title 1 ....................1
1-2- Title 2 .............2
1-3- Title 2 .............8
2- Title 1 ..................10

Help please !!

Thank you very much
