Can't clear "custom" date field?
I'm setting up Calibre to work with the Kindle that I'm giving my wife on Christmas.
I wanted to create a custom date field called "Date Read", and did so with no problems.
Well, then I wanted to set up some custom searches related to that. To do so, I had to put in some dummy dates on a few books so that I could make sure the searches operated as expected.
#dateread:<2010
#dateread:<2010-05
#dateread:false
#dateread:true
These all worked PERFECTLY!
But now that I want to clear the date fields, I can't find a way to do so! I can only edit the "date read" field. I can't clear it out again.
I have tried deleting the value, right clicking and selecting "cut", I've gone to "Edit Metadata" > "Edit Metadata Individually" > "Custom Metadata" and tried to delete it there but just can't do it.
Is this a bug or am I missing something very simple?
