This is an old bug that is still there. Something similar happened to me, almost an hour ago, but worse, lost access even to chat, I couldn't tell to my teammate I glitched and he was struggling with a high level Corrupted Jackal on Steel Path alone and got angry at me for being "useless". But I found out that pressing P to view mission progress, the chat icons appeared again although it can only be opened with mouse click.
I'm from South America playing in Europa server, because last time I played in my region, there was so many toxic last second ditch trolls in SP Circuit.
