Bed leveling issues N4M

The left side of my bed seems to be always to high. This .4334 if the best I could archive after a bunch of leveling. I already leveled the X gantry which was a little off and I though that would be the problem but nope. And is always the same exact spot that is high.

I used Bed leveler 5000 and as you can see the mesh created with Bed Leveler 5000 says 0.389, which is different of what Fluidd says ???

Any advice would be highly appreciate. Thanks!
