Eccentricity on embed plate due to shear load

I have a difference of opinion with my senior engineer regarding eccentricity. We have a situation where a double angle connection is used to attach a steel beam to an embed at a concrete tilt panel wall. He says there will be no tension in the embed studs since the eccentricity of the shear load can be neglected as it is similar to attachment of beam to a column. The load is due to a composite beam attached to the face of tilt panel wall. The steel deck of the concrete slab is just above the tilt panel wall.The very first row of studs has an edge distance of 2" from the top of the wall. If I run the analysis using ACI 318 appendix D without the tension loads the connection is fine. However, with the tension loads the connection fails. If I ignore the first row of studs the connection is fine (edge distance is now 8") with the shear and tension loads. Is this ok to consider? Should the connection be designed without eccentricity ?

I changed the edge distance to 4". I designed both the connection for both shear and tension
