Global Areas/stacks NOT EDITABLE after upgrade

Permalink
Hi Ive updated to 5.6.3.1

And now I dont have borders around my global areas / stacks in EDIT mode
How can that be fixed

this is my template html...
div class="about footer-boxs">
<?php $block = Block::getByName('Omos'); $block->display();?>
</div>

REGARDS
