Problem with links in the menu, what's the matter?

Question

Bootstrap

Good afternoon.
there is a site (so far locally), there is a menu. The problem is if the menu goes to 2 levels, then the links of the 2nd level plow the norms, but if I add another one to the 2nd level, then the parent of the 2nd level stops working links.

When you click on a level 2 link, the open class is added to it

Attention experts, a question. How can you profile? To links worked out everywhere.
