A friend makes the following comment to me. The version 5.33, generates errors in the massive substitutions of data. Being one of the new features of the version, in the massive modification of metadata, it usually removes the author names from the library.
Remove authors in bulk substitutions.
On three occasions recover only by reloading the metadata from the files. If you look there is only one author. ( Picture 1)

The problem arises when Python search expressions are used in saved searches.
To be able to do the substitutions in bulk, by characters, this is the correct way. With character matching in the * Search Mode * option. When done by * Regular Expression *, it gave me error in the use of the brackets. (Picture 2)
When done with some punctuation mark that Python registers as a special character, it completely deletes the substitution field in * Regular Expression *, (Picture 3).

The bad thing is that it clears the field in * ALL THE LIBRARY *
The strange thing is that when python grouping characters are used it does fine in both forms of * Search Mode * as you see it here. (Picture 4)
