Problem description:

Can anyone tell me how to fix it as well as what is causing it? All the other mobs are stationary , I'm the one moving.
I think you might be using TOPDOWN_LAYER on those other mobs.
In response to Kaiochao
This is true. All Mobs have it. The isometric turfs are elevated so that's the only way I could keep my characters above the turf.
In response to Kaiochao
This is the effect I get without topdown_layer

Hmm. What to do?

I'm guessing you're new to isometric maps? You should lower the pixel_z of your turfs so they're no longer elevated. If you set it to the -height (in the z direction, which is directly upwards, but it's negative so you're moving it downwards) of the turfs, then the top surface should be at true 0 altitude.
Ah.
Yea I was messing with the world.icon_size to try to fix it and was getting all kinds of interesting results...
for instance.
That fixed it. thanks for your help.
