Hello Hecfran,
Thanks for reaching out with your issue!
I’m not sure where those lines are coming from, but the first thing I would test for is a plugin conflict.
You can do this by deactivating each plugin on your site one by one, clearing your cache if applicable, and viewing the gallery to see if the lines go away.
I would also suggest activating a default theme such as 2019 to rule out a theme conflict.
Let me know what you find!
Thank you very much for your response Kevin.
I have done what you tell me and the problem remained. I have even configured the plugin in different ways and nothing.
Until the simplest solution it was correct. It is not enough to paste the shortcode directly into the block, but must be done within the shortcode mode of the wordpress block.
Maybe it was a mistake of mine from the beginning, or a wordpress flaw. The truth is that now it works and I am happy since I really like the plugin envira.
Maybe someone will be utility the solution, I hope so.
Thanks again and regards !!!
Hector
