Hi rborst
1 - As I can see the ticket logo is showing now, did you get it solved?
2 - For the head action, you can go to Backend >> Extensions >> Templates >> edit template style you're using
Navigate to Layout Settings >> edit the 'header' block, you will see this code:
<div class="head-action d-none d-sm-inline">
<jdoc:include type="modules" name="head-action" />
</div>
And remove the d-none class there:
<div class="head-action d-sm-inline">
<jdoc:include type="modules" name="head-action" />
</div>
Then clear all caches.
