problem with data mapping and eye icon to make pw invisible

I have to issues with your plugin. I am testing it together with the buddypress plugin from wordpress.
1. the eye icon to make the password invisible. When you click on that icon the whole boxes who came after this icon moves down and up when you click again. I had a look how others do that. I wonder why you use an a-tag for that and not a spam-tag. Anyway, could you make it not moving when clicking?

2. When you install buddypress, wordpress has two user settings pages. One with the main wordpress user data and one with the user meta from buddypress. When you make changes after using your registration plugin which maps its data with the buddypress meta a member cannot access his settings page and profile page anymore. Then you have to delete this user. If you make changes to the user meta on the second settings page as an admin everything ist fine. Is it possible to make this fields inaccessible at the first wordpress user settings page that to avoid this problem by incident?

I think the reason for this is, because the maping for the user fields isnt done anymore after registration.
