delete spaces in author names

[Celia]

Please delete the spaces in Christina Clancy and Florian Schneider between their first and last name (there are two extra spaces when I add these)

Librarians can't correct the profile of a GR author.
One or more extra spaces in an author name are used intentionally to separate different authors with the same name.

However, for Christina Clancy, there seems only one author with this name on GR (and another with an initial). I'll contact GR Support to have the GR author moved to the 1-space profile.

For Florian Schneider, there seem to be (at least) three different authors with this name on GR, so the spaces are required to keep the profiles separated. If there are books on a wrong profile, they can be moved to the right author.
