why are my walls not creating a neat corner when I use the intersect tool?

Hi there, I'm trying to make my two walls connect - i tried unhiding everything and there is nothing in the way so i dont why this is happening. Please provide some options.

The reference line of one wall may not be touching any part of the other wall.

Or you have turned off the on-screen display option for 'clean wall and beam intersections'.

Update: I figured it out - there was another wall in the forefront confusing the mix - so I changed the interesection priority of the external walls to be higher than the internal walls and they connected.
