Hmm, I've confirmed the issue that the " Prevent logged-in users from editing from this IP address" checkbox is checked if you view the block page again.

However, if you go to the block page again, uncheck that box, change change the block duration, then click "reblock user with these settings", the new block log entry says "autoblock disabled" - so apparently it's only the initial block which disregards the checkbox status.

So you can do that to fix your problem this time, but the whole thing is definitely a problem which should be fixed. You can use Special:Contact to inform staff, and include a link to this thread.
