No, that didn't seem to be the problem for me. I also went through and changed or toggled pretty much every display setting/value to see if any of them may be glitched for me in some way but with no luck. Reinstalled the plugin and remade feeds, etc.
Thanks for the reply and input, anything else you can think of please let me know!
