Export/Import database problem

[dev-hit]

As also indicated in issue #18035 by another user we are experiencing a very similar problem.
When we proceed with the export of a database (all its tables, views, procedures) we get errors when restoring the database.

Often fields are duplicated when we have GROUP BYs (e.g. SELECT ... FROM ... GROUP BY idRispidRisp) or DESC values are mistakenly inserted by the system to our ORDER BYs (e.g. SELECT ... FROM ... ORDER BY idRisp ASCDESC) which then lead us to an error when importing queries into a new database.
We are also experiencing errors when exporting/importing some views. Conversions are in fact added by the system automatically, but they are not present in the views we wrote ( ... CONVERT(name USING utf8mb4) ...) and which cause us an error when importing the query into a new database.

Additional information:

We perform the export in SQL format.
