Yes, problems with entering flight plan manually into the MCDU. I don't use simbrief. I use real world routes from flightaware. For my case it was entering a VOR waypoint flying in the US. I select previous fix, then click "enter next wpt" and enter the VOR fix, it'll populate duplicates but both are exactly the same. I chose the top one and then it automatically goes right after my departure airport instead of the next waypoint. Please check and hopefully gets fixed on the next update.
