As designed Bug in development mode when create new or edit option

[infis]

In a development mode ($debug = true in config.php) at option addition if to choose ' Edit Format ' - ' Named Template ' and to specify in ' Format Parameters ' the incorrect format the option will remain, but it will be thus invisible. Accordingly, it can't be changed or removed, and also it will be impossible to create a new option with the same ' ID '. The unique decision in that case - removal of group of options.

I offer in a development mode irrespective of a correctness of display of an option always to deduce the name or ID options with possibility of its change or removal.

You can always access the option editor with admin.php?options/edit-option/{option_id}

This is the intended behaviour, as options may be set to output nothing.
