https://bbpress.trac.wordpress.org/ticket/1819 gave a solution to the problem that I am pretty sure worked. However, I just want to note that the issue still exists and help anyone that might be having this problem.
If your replies are being covered up like the picture above, you can fix it by adding the following comment into your bbpress.css file (wp-content/plugins/bbpress/bbp-theme-compat/css/bbpress.css):
#bbpress-forums div.reply {
height: auto;
}
As with the author of this bug request, I am also using custom-community.
