I have started in “Managing merge conflicts” course. Everything was fine untill I went to the pull request of step 6 instead of 5 (by mistake). After doing step 6, going to the next step. I was surprised that it was labeled with step 5 (actually 5a). I did not noticed that I missed a step previously, but notices after doing step 6. Now (after doing step 6) I have done step 5 (5a and 5b). but I cannot find a way to resume. going to dashboard I see that I should do step 6 (which, again, is alredy done).
How can I reset the couese progress?
