'guid' field of wordpress posts table corrupted

I’m always up to date with versions of Wordpress, Avada and all plugins.
Last November I started to have problems saving pages. Rebuild pages solved the problem temporarily. Last fews days, with lots of testing and experiment, I found that that the field ‘gui’ of the posts table of some pages was containing the first 255 bytes of the ‘post_content’ field.
Changing the value of ‘gui’ field to something similar to other pages solved the problem.
