In this case, there is usually something wrong with the tab stop, so how to align the page numbers?

Method 1: Borrow tab stops.

Select the misaligned content, then find the tab on the ruler and drag it to the appropriate position. (Hint: Fine tuning can be achieved by borrowing Alt key)

PS: Of course, you can also click Start-Paragraph-Tab Stop to clear the previous tabs and reset them. For example, the character position set here is 40, and then click OK.

The second method: modify the directory format.

Click Reference-Directory-Custom Directory, and in the pop-up interface, select General-Format-Formal, and click OK.
