I assume you can unlock a multi-segment selection that also includes unlocked sections. If not let me know and I will pick out only the locked ones. It was taking a long time to find them all. Thought I would try this way.

Most of yours have been like that. It shows the box as unchecked, so I have to check it and then uncheck it. It should leave everything unlocked.
