There was a minor styling update in version 1.3.0 that could cause issues if you have used custom style generator for version 1.2.0.
There is now a new class .bhr-content-layout which wraps the entire content. If you noticed your styles are different after updating to version 1.3.0 you can simply replace bhr-wrapper with bhr-content-layout in your custom style and everything should work as expected.
Here is a basic HTML structure of the data:
<div id="bhr-post-X" class="bhr-wrapper">
<div class="bhr-content-layout">
<div class="bhr-header-wrapper"></div>
<div id="list-hours-X" class="list-hours"></div>
</div>
</div>
