Problems with Agenda toolbar on iPad Pro

What I did:

What happened: for some reasons, the toolbar of agenda lies under the bar that allows to swipe a window. If I try to choose the bullet points, the window with agenda disappears every time. When I reopen it, the bullet point will be there, but it‘s a little bit annoying, that the window closes every time.

What I expected:
