Photoshop CC Annoying blue outline around my tool line

I'm coming here because I don't know what to do anymore. Before when I used to use the Line tool (U), I could do plenty of line fast and easily without the annoying blue line around it disturbing me when I work and create a shape layeyer afther that (which never happened to me before).

Does anyone know how to fix that? I reset all my settings, closed and opened again PS, reset the tool line, reset my workspace, search on google... Thanks in advance if someone can help me clear that out
