hi,
there is a problem in your Html if you implement it in correct manner then the problem can be solved but we don't have that much time to correct the code thoroughly so, for now, I am giving you custom CSS for removing the <br> element from the code.
add this one---
.textwidget p a+br {display:none;}
it will work for sure check:
