Spain country pack and it's dial plan is not supported on BE3K. You are trying to make it work with Open dial plan mode. Support of a new country using Open dial plan mode is not supported. That's why you do not see tools to bulk delete all patterns and other things.
There are also other things related to dial plan which may still be there. We can try to debug and make it work. But I will suggest not do that, simply because it is not a supported mechanism.
Instead you should wait till the Spain dial plan is supported.
1) As it exists currently, you can not do initial install with US dialplan, blow out all the configuration and reconfigure it for some other non-supported country dial plan. Somethings may work, but others would not. And it is not a supported configuration.
2) Open dial plan is available with 8.6.4. It allows one to add, delete, modify additional route/translation patterns for supported countries. It does not allow one to support dial plan for an unsupported country.
How did you learn that Spain is a supported country?
