I dot see in the mesh display the edge lenght,face angles

I have a model that i start modifying with bmesh , but the model looks inaccurate, so i try to activate the edge length and face angles and huh? doesn’t work
No way? why?, and i insert other object and works perfect, thought it could be coz am working with the add on bmesh but i add an ngon and i see the angle and length information.
Why?

Ohhh… the solution was very easy… just select the model but the face dooohh… i feel like a penguin am sorry X_X
