Could you make sure that the image is large enough to be used on both Twitter and Facebook? That image should be at least 300x300px.
If that doesn’t seem to help, could you give me a few examples of the posts where you experienced the issue, so I can take a closer look?
If you want it to remain private, you can also contact us via this contact form:

Thanks!
The image size that I am assigning to the WP post as “imagen destacada” is 2705 x 403 px.
You can see the FB post (“Prueba JetPack 04”) in https://www.facebook.com/samctOnline/?ref=bookmarks and the TT post in https://twitter.com/SAMCT_OK
How can I fix it?
Thanks.

Thanks for the extra details.
It looks like the image wasn’t there when you first published the post, and when both Social Networks crawled the post:

Did you add the image as the post’s featured image after publishing the post, or do you use a plugin to automatically create that featured image for you?
Could you try to publish a brand new post, and define the featured image before to publish the post?
Let me know how it goes.
