It is a bit hard to tell without seeing the actual project. And how you have done the anchors but if you have done them by giving an element and id like kandidaten and then having the action open #kandidaten Then I think that you now may not have them.
When I do a test like the above, in the debugger the aria-flowto for the button points to the id of the element with the id.
Yours all point to hype generated ones. Now I am not 100% about this but that may be the problem.
This is the div of my Button that jumps to the Anchor:
<div class="HYPE_element" id="hype-obj-EQq0uLSxgKmhUeVo" role="button" aria-flowto="bottom" style="pointer-events: auto; position: absolute; z-index: 2; border: 1px solid rgb(160, 160, 160); padding: 6px; -webkit-user-select: none; background-color: rgb(240, 240, 240); word-wrap: break-word; display: inline; font-size: 13px; text-align: center; color: rgb(0, 0, 0); cursor: pointer; overflow: visible; width: 90px; height: 15px; top: 59px; left: 260px;">Button</div>
The element id is named bottom and the anchor is #bottom
