Hi,
First of all, really sorry for the delayed response. Support crew is on summer vacation thus it causes some delay on replying inquiries.
I left alone and trying to catch up. But, starting from August 15, vocations will be over and this problem will be resolved. Everything will be get back to normal like before. Normally our support-get-back time is within 2 business days.
I need to see your website alive and see the course codes & CSS rules. This problem is happening because of your Joomla Template. I can't provide you any solution without seeing your website alive. Screenshots won't help me.
Regards.
