Hide duration time in curriculum page

Hello! I am creating a course on my website and noticed that the lesson duration is displayed as shown in the image. I would like to hide that information, but I can't find a way to do so. Additionally, the displayed time does not match the actual content duration. All the lessons show 0:11, but the audios and videos in them have different lengths. Could someone help me remove this information from my course?

Thank you in advance!

Sorry that solution doesn't explain what we're supposed to do to fix this.
