AddictedToPrint

Hi all, When using Cura to slice my prints, all the settings are set to using the Generic PLA, which is what is in my UltiMaker 2+ Connect. When I insert the pen drive and select the print, the screen comes up with a message that says: Print set to Unknown PLA, Generic PLA loaded, continue anyway? I haven't changed the settings so I don't understand why this is happening. I left a print overnight, having selected print anyway, and came back down this morning to find only part of the print completed but the screen said that it had finished. I think there was a blockage partway through that I have now cleared. Please help!
