A project migration glitch

Question

I encountered a weird error migrating a project. The migration went fine, Paratext reported the project had migrated, but then it showed this error when opening the project.

It turned out there were some extra characters in the scripture reference settings (viewed in Paratext 7.5) that was causing this.

When I cleared out the extra characters in Range of verses in 7.5, then deleted the project from 8 and remigrated it, I had no problems.
