The shape of the raft is abnormal.

As you can see in the image, the raft does not cover the printout.

Is this a bug?

In all likeliness, your model does not have a perfectly flat bottom. You can either fix the model, or move it down into the buildplate a little bit (say 0.1 mm)

Maybe turn over the part?

A part of the object is not touching the buildplate...  redesign, move it down into buildplate or flip it over...

When I rotated the part, it read 180 degrees. However, it seemed to be tilted slightly. I repositioned it and the raft is now normal.
Thank you.

to make it easier when using the rotate option, select the "select face to align to buildplate" option...
