Classic I literally can't roll for items sometimes.

I just did LFR today, a ring and wrist items dropped, both of which i rolled need for, but both dropped twice and i wasn't able to roll on the second one at all when other raid members could. I had lower item level than both items equipped. I only saw 4 items instead of 5 in the roll window, the 5th item (the duplicates) i couldn't roll for for no apparent reason. I'm certain i rolled only for one and i didin't get the chance to roll for the other.What could be the cause? I'm using Naowh's UI. via /r/wow https://ift.tt/uIFis7l
