Somewhat common. Think about how much play may have been in the old gear + rag joint etc. If the alignment was done with sloppy worn out parts, putting new parts with much less tolerance stack in place can cause the alignment to be off.

The same thing happened to me when I had a new box installed.

Inspect every part of the steering system, make repairs or replace parts like tie rod ends and toe adjusters if needed, then follow up with a new alignment.
