all "Level Buttons" RESET

hallo,
all Current Level Buttons of all Lessons are RESET. It was my 1st lesson to hear and test. I don't know what's the reason and what's the Impact. Thank you in advance for Information

I'm not sure what you are saying (or asking), ingrid.

The system looks normal on my computer. Completed lessons show green or whatever level I achieved. I have to press the reset button to clear my old score and take the test again.

thank you Dan for your quick answer. I must have pressed it. Now I know how button and colours work. :-)
