hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
After debugging long time ago, it seems like you added this `Calendar` in this settings -> Exclude categories from frontpage, you can take a look of my screenshot below, then causing this issue is because you should put category id instead of category name -> ( To exclude categories from being listed in the front page, enter a comma separated of category id's. E.g: (1,2,3) )
After I put back id = 8 in that settings, it display correctly now, can you give it a check now?
