Unusual moment diagram for slab

[jordan.v.dimov]

If you take a look at the pictures below there is a very unusual jump in the momentum diagram, I mean that there is no reason for such a jump. No concentrated moments or what ever difference. But diagram looks wierd.

Any idea why and what to do to fix that issue ? This is not the correct momentum diagram i'm sure !

As far as I can see the projection of the results is done on the automatic direction. Try to change it to e.g. Direction X (or make sure that the local X axes of the top panels are in the same direction). If that doers not solves the question attach the model please.

Look at the local axis of your beams, they are not set in the same direction -> I think the X axis have are in opposite diretion that's why one is negative and the other positive. turn it same direction and the continuity will be restored.
