Remove separator in the text

Hi,
I’m writing some post and I always find the same problem. There is a separator in the text which separates the first line from the rest of the text, without including the titles. This is very annoying since what is written after the title are paragraphs and there is no way to control that separation or by html. Attached image. How can I remove it? Thanks in advance.

Hi!
Sorry I am answering so late.
In adiccion of the picture I attached before, this separator breaks some blocks that I put in my posts. For example in this one: https://aeternalecturas.com/resenas-de-libros#After_de_Anna_Todd the separator is between the imagen and the button, so it seems that the button doesn’t belong to the image above. It’s confusing for the user.

In this one, I don’t even know why so many separatos and I don’t know what to do. https://aeternalecturas.com/noticias-literarias/resenas-literarias

Please, help me with this. It is exasperating.

Thank you so much!
