Sorry, as I double-checked and you're right, like you pointed out, you had completed them.
So, that can't be it.
Yeah, restarting isn't great, so let's try re-doing this instead.
You have the proper change it seems in your release branch
but, that's not under the v1.0.1 tag
So first try just re-doing 3.4. It may make a mess, but worth trying before re-doing level 3 in its entirety. You can also follow the overview linked to at the top of this thread. Let us know if that works!
