I've fixed the positioning problem for the next release.
FYI:
Generally speaking, nesting blocks is somewhat problematic as a block might contain any number and type of shapes and parts.
If a block contains exactly one part (i.e. a single outline, optionally with islands), the nester behaves exactly the same as if the part wasn't in a block. This is supported for convenience.
If a block contains multiple outlines, intersections, etc. as "block 1" in the example, QCAD/CAM creates a convex hull around the entities and nests that. This usually does not lead to the best result.
