So this is the problem that is happening, your video showed exactly what happens, but it should appear otherwise, I will show 2 examples.
the first is what should be the page of events: http://escolamaieutica.com.br/events

see example: https://postimg.org/image/6vbwoophvf/

so should be the page of events, with this calendar as there is on the homepage, in the footer of it

now in the page of the event “Feriado da Conciência Negra” in the link: http://escolamaieutica.com.br/event/dia-da-consciencia-negra

It should look something like the next image: https://postimg.org/image/5n22f17bd7/

A page with the date and time of the event with a photo of the event and the description of it.
Note that if you access the news page on the site will appear the same thing that appears in the events.

I think there must be some incompatibility with the The Events Calendar plugin, but I can not find it.

I hope you help me
