Remove separator in the text

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 there

Hope you are having a good day and thank you for your question
In order to check your question i need to see your live website, please provide url and i will take a look

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: 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.

Please, help me with this. It is exasperating.

Thank you so much!

hey there
