Udemy Error Unpublished Lecture on Curriculum

So today i've done uploading some of my course on udemy (this is my first course), it's about 8 GB plus s it takes a while to finish. After the uploading proses was completed i got 1 warning at on of my lecture (below picture). Then i try to search for the answer, luckily i found this forum discussion on udemy so i  manage to try and fix this problem.

Basicly, the problem is the course type. Let's look this way, when we first upload a video it's by default use free course type and if we want the create free course then we have limitation such as course time, based on the article max time is 2 hour but in my case i have 3 hours and 10 minutes and the warning just appear on 1 lecture so i assume the limit is 3 hour.

So to solve this problem i try to change my course to paid one. And for change that course type you need to connect to a payment service (paypal or payoneer).
