How to recover the slider of the rooms?

Hi, I’m not sure if this is the right place for my question, but I can not find a way to solve this problem.
I come to ask you for advice.
After more than a month working on the project, delete the images from the “library” and the entire slider will disappear.

At this moment, I am trying to add the images to the slider that the different sections of the theme have, like the rooms.
Edit the slider with which the site starts (https://lasmimosas.org) has been simple, because in the editor you can see the slider corresponding to this section: [rev_slider alias = “howello”]

This is not the case in other sections, such as on the same page, the section at the top of “rooms” and “Our services”.
The editor shows only what is seen in the capture: https://ibb.co/vDB15PF
As in the editor, there is no way to see what the slider is that I need to edit, as in the main slider: [rev_slider alias = “howello”]
The same happens in the rooms, the following is shown: https://ibb.co/Z82rt0p
And the editor does not give me any option to know which is the corresponding slider. You see it in the capture:

How can I know the slider that corresponds to each section?
One option could be to complete all the existing slider with the new images and then correct and change the necessary ones for each section.
But for this you should spend a lot of time. I’m sure it’s very simple, but I can not find a way to do it.
Can you give me some advice on how to get what I need?

Thanks for the support.
