This image depicts the issue using a tailored item sitting on the tailor's workbench.
Affected productions stations are sculptor's table, tailor's workbench, and smithing bench.
Steps to reproduce:
1. Build one of the three production stations listed above.
2. Create a bill and prioritize a colonist to start working the bill.
3. While the colonist is still working the piece (or even when not working the piece), right-click the piece as to prioritize it. (You may also right-click an unfinished piece on the ground - it doesn't have to be on the table.)
4. Observe three lines, Prioritize smithing at Unfinished..., Prioritize tailoring at Unfinished..., and Prioritize sculpting at Unfinished... . Some lines may say 'Cannot prioritize'.
Expect only one relevant line to appear and without 'at'.
Thanks to anyone (at least one person) who posts to confirm the issue.
