Is this a bug?

Is this a bug seems like the square line don't match with the item

No. Angled blocks do that. You can make them fit better in editor or you can freeplace them in game using "V" key....or you can simply replace the block you are trying to match with a square block in this case. Technically the game sees it as snapping one invisible cube to another in a grid pattern. Freeplacing allows you to move around the boundaries of the white lines in that cube.

If you look at it more like this, perhaps it will make more sense. 

[spiritchaser28 918]

When a block from one cube crosses over the boundary of another cube, it's called a collision. Collisions take slightly longer to load. If there are only a few hundred collisions, most times the lag is not noticeable, but if there are thousands and thousands of collisions that's when you notice the amount of time it takes to display the blocks correctly.

If you are using editor to create, there is an option that allows you to "weld entities".....this feels sort of like merging all the cubes...but technically what it really does is decrease the collider count. Many blocks placed in game naturally weld over a set amount of time, while others placed on vehicles weld as soon as you assemble the vehicle. Also, welding in editor allows you to move and place multiple blocks at a time. This is similar to another option called groups. Multiple blocks can be in one group, however a group does not decrease colliders in the same way as welding decreases them. I hope that all makes sense
