Bugreport: Learning from multiple source language confuses Duo.
To showcase the “German -> English” duolingo I “started learning” it to day and took the placement test. Afterwards I returned to French only to find my progress was reset. Well, it wasn't -- On closer inspektion I found myself inside of “German -> French” instead of the usual “English -> French”.
Apparently, Duo found it fitting to switch my French class over to German as well. A behavior which is unwanted and confusing. Can you try to fix this? (And make sure it is stable for three and more source languages as well ;-D )
