It seems to me that there is a strange behavior with the issue templates as well:
If you go to https://central.owncloud.org/ and click on the "New Topic" button on the top right nothing is shown. If you chose e.g. the "Hosting area" category the template is popping up.
But if you chose a different sequence and typo something in the textbox before choosing the category and then chose the category afterwards the template is completely missing.
I'm not sure if it e.g. makes sense (or even possible) to show a short text after the "New Topic" so users get informed to first chose the category before writing into the textbox?
