[Doubt] What is this dotted selection?

Greetings,

As I am still learning some basics. I stumbled upon this:

I can’t take it out without deselecting and reselecting, it stays that way and I don’t know how did I put it there.

It is just some doubt as I was able to finish the model with that thing there.

What’s the problem? All i see is the 3d cursor, 3d manipulator, origin point and your mesh. Nothing out of place as far as i can tell.

active element(face)

The blueish face is the last element you selected, it makes it the active element, doesn’t change much unless you use a tool which uses it.
