Hi Lee,
Thank you for bringing this question to our attention. I made some research and I found these two topics that answer the same concern:
It seems there is no solution to set an automatic order. However, you can set manually a specific order by using the order field in each forum. Please find the attached screenshot.
Concerning the topics, please be aware that you can set some topics as Sticky or Super Sticky to display them on the top of the list. In case you want to know more about this, this topic from bbPress support might catch your attention: Understanding “Stick (to front)” and Topic Types: “Sticky” and “Super Stick
Please note that this issue is related with the use of a third party plugin, not with the use of your theme. As theme authors, the installation, setting or debugging of third party plugins isn’t part of the support we will provide.
To go further, we invite you to ask for more help from the plugin authors and post your request on their support forums:

We remain available for all support requests related with the use of your theme.
