Hmmm. Can you share it to help diagnostics? You can share it with me privately if you don't want to make it public. Sending me a message via Tawk should allow us to get that started. If they are in a copper area, try **Rebuild copper area**. Have you changed the schematic and then imported any changes that might have affected the net names or reannotated any prefixes? Have you changed the grid at all (accidentally pressing the `G` key is a prime suspect)? What does the Design Manager show? Try saving, closing and reopening.

Problem solved . . . it appears that some artifacts can remain after importing changes to the schematic. I closed the PCB and then converted project to PCB again. Ken
