Unable to correct title as it was first entry for a new author

I incorrectly entered the title of a book by Dianne Minnaar as "Teach Yourself *Colour* Calligraphy". Soon after I spotted the mistake, and removed the word "Colour" from the Title and Summary fields of the book page.

However, the incorrect title still shows up in the Work Information field. And when I click the author's name in that field, the author page (https://www.librarything.com/combine.php?author=minnaardianne) informs me she is the author of 2 books - one with Colour in the title, and the other without.

How can I expunge this incorrect title from LibraryThing?

Looking around, I do see other works by Dianne Minnaar:
https://www.librarything.com/search.php?search=Dianne+Minnaar&searchtype=new...

These all seem to be the same work as the one I entered (either original or translation). I'm not sure why none of these titles appeared on the author page...

>1 rmilne: You can't delete the incorrect title with "colour" in it but it shouldn't pose any problem, it has become a zero copy edition and won't impact on anything. I have combined the 2 instances of the author name Dianne Minnaar and then combined the 2 works as Teach yourself calligraphy, does that look correct?

>1 rmilne: You need to click "Recalculate title/author" (under Advanced on the right hand side on a desktop) to change the title in the Work Information field. I've done this for you and it should have changed now..

>2 rmilne: Previous entries for Dianne Minnaar have her listed as Dianne Minaar (last, first) wheras you have listed her as Minaar, Dianne (last, first) - which appears to be correct from Worldcat. As a result there were two authors on LibraryThing - dianneminnaar and minaardianne. >3 bernsad: has combined the two names.

Thanks, bernsad and newcrossbooks, for those quick responses - I'm happy with the fixes and changes you've made.
