I took a look at your schedule. I think the reuse system is having a hard time figuring out what to make of your pattern of shifts. The reuse system looks for shifts that occur regularly week after week. If a shift only takes place once or twice during the block it's hard to deduce a pattern from which a new set of shifts can be created in the new Block.
The reuse system works well for the majority of typical cases, but in a situation like this, where you have a large number of different shifts that take place only once in a while it is unable to work.
Sorry about that! There isn't much I can do here.
