25 foot long retaining wall, 3 feet high. There is a gap between two bricks which is one inch wide and 7 inches deep. Layer of bricks sits on concrete blocks. All other joints look good. Maybe this was caused by settling or movement. Should I just fill in with mortar mix? Pic is looking down at gap. Sidewalk on left (3 feet below) and soil is on right.
