The input editor gets corrupted automatically (BLACK VERSION PRO)

Hello, good morning, nice to greet you.
I do not speak Spanish, I am helping myself with the Google translator.
Please your urgent help.
The input editor is automatically damaged when the logo is uploaded in the mobile version (BLACK VERSION PRO)
After having investigated and restored several times from Cpanel, detect the following:
Something super strange happens … the “width” of the editor of a new post is automatically damaged when the text in the mobile version logo area (which comes when loading the demo) is changed to a logo image (normal and retina)
Please look at the attached images. Please your help to solve the problem.

Please, I beg of you, your help.
I had to disable the “gutenberg” editor. But my client wants to use the gutenberg editor. The only way I can recover is by restoring the Backup in Cpanel, but every time I change the logo of the mobile version the editor is damaged.
