How can you remove this setting from a KeePass entry?

[jds13]

If I clear the key and try to save, I get a pop-up dialog:
Invalid Otp Configuration! Your configuraiton [sic] does not contain a secret, A secret is required!

It should be possible to clear the OTP setup by saving the configuration with an empty secret key... Or "Delete OTP setup" should be added as a context menu item.

Thanks very much for this great product.
