Inline Page Linking is not working

I’m working on this issue many hours now and can’t come up with a solution. The link to #login works but the link to #register doesn’t work. I can’t figure out why. I’ve been working with Framework7 for a long time but I haven’t had such a problem yet. I’m working with v1 because it is a big project. I have reduced the size of the project here. Does anyone have a solution?
