A href problem please help

Hello guys, 

I am new to JQuery use. I am making my website and i have this problem: I hosted JQuery file from google, and it works.. my Back to top arrow and navigation bar change works perfect with it. BUT JQuery blocked a href links from my site (Example social media icons, contact icons etc...) .. If i delete that link from HTML file links works fine, but without it my arrow and navigation menu don't work. 

Please help me how to have both of those tnx in advance.
