Fix hueman sidebar with EventOn extension

Hello, I allow myself to come to you because I am currently in contact with the support of the EventON extension because we cannot find the solution to a bug which would be partly related to the theme Hueman (free version). When I display an individual event, the right sidebar appears empty … while on an article or a classic page no difficulty. They are partly blocked because we do not understand how the theme displays two sidebars on the sides with content in the middle. Do you have anything to bring to me that I can point out to them? Thank you in advance !
