Several elements of gutentor do not work

Hi, please can you help me:
I'm having problems with Gutentor:
1. In lists the right margin seems to be infinite.
2. The image widget still doesn't display the image well
Anyway, it's chaos, it doesn't work and until now I can't finish laying out a page?

It has something to do with the fact that it is installed in version 6.1.1 of WordPress, but it works on another site with the same version.
