@iazrt The Showcase theme (my favorite) does the same thing as well and also has a blank tag which I just removed. Just search for >< and you'll easily find a blank.
@mktaia You should probably take this to their forum - http://orangepi.club/index.php
I have both a raspberry pi and an orange pi, myself. Orange Pi is still on Jessie, whereas Raspi is now on Stretch. There are going to be differences.
Controller pictures are also .svg just as the logos are, so I don't think that is the issue unless the there is memory limit reserved for the theme and the svg is hitting it.
