Issue with the Header Bar after activating an Anchor

Hey Atlassians Team,

We are using 5.1.3 at the moment. The Anchor macro is not working correctly and we want to ask when it will be fixed.

Issue:

A part of the Head Toolbar(Logo, Spaces, People, Browse, Create) will disappear after activating an anchor. To let the Toolbar appear again, is just possible if we leave the page.
The 2 screenshots will visualize what I am trying to explain.

For futher questions just contact me (viktor.miruchna@zalando.de),
