This is where the end repeater does not un-power but if there is one repeater it is fine.

Question, then why do the repeaters on 4 ticks up to the last one change state but not the last one?

Looks like MC-54711.
A repeater also take some time to unpower. In this case, it takes longer to unpower, than it takes to repower.
