I'm writing a thesis on a new course I'm finishing and the ToC is not aligning properly, at least some of the items.

As you can see in the image, item 3.3.1 is not aligned properly. I've selected the whole sentence and chose Heading 3 in the style bar, after the before the sentence wrote 1. to make start numbering. with the mouse chose Continue numbering and clicked 2 times on tab to make it the number I wanted. After refreshing the index, that items became like that. can you guys help?



I've posted an inmate and don't show up
