Problem Building Query

Hi, 

I'm trying to download all patents filed under Y20A. The query builder created this query for me: 

https://api.patentsview.org/patents/query?q={"_and":[{"cpc_section_id":"Y"},{"cpc_subsection_id":"Y02"},{"cpc_group_id":"Y02A"}]}&f=["patent_number","patent_title","patent_abstract","patent_date","patent_kind","patent_type","assignee_city","assignee_first_name","assignee_id","assignee_state","cpc_section_id","cpc_subsection_id","cpc_group_id","cpc_subgroup_id","cpc_category","cpc_subsection_title","cpc_group_title","cpc_subgroup_title","cpc_first_seen_date","cpc_last_seen_date","cpc_sequence"]&s=[{"patent_title":"asc"}]

However, I get zero results using this. Does anyone understand where I have gone wrong here?

Many thanks in advance!

null fields

It looks like something is wrong in the database, most likely with the recent data load.  This query q={"patent_number":"8674214"}&f=["cpc_category","cpc_group_id","cpc_section_id","cpc_subgroup_id","cpc_subsection_id","cpc_sequence"] used to work but now returns null cpc_group_ids etc,

{
    "patents": [
        {
            "cpcs": [
                {
                    "cpc_category": null,
                    "cpc_group_id": null,
                    "cpc_section_id": "H",
