Using AB 5.20 with QP EOD 
    data, the Sectors, Industries, and !IDxxx charts are all mixed up.  For 
    example:
1. For AB shows 13 Sectors, including two Utilities and one 
    Transportation.  The brokers.sectors file contains only 11 items, only 
    one Utilities and no Transportation.  The first Utilities contains 17 
    industries, only 4 of which are utility related -- the other 13 are 
    retail.  The second Utilities contains the same 4 utility related 
    industries as the first, but with different companies, all of which have NO 
    data.  The Transportation Sector contains 9 industries with a total of 
    23 companies, only 4 of which have any data.
2.  AB shows 182 
    industries, many of which show up in more than one sector.  
    Broker.industries has a total of 151, including Undefined.
3.  
    AB shows !ID001 through !ID198, however !ID154 through !ID198 have no 
    data.  QP3.1 shows only !ID001 through !ID153.  (I would expect 
    there to be a one-to-one match of !IDxxx symbols to industries (just a 
    guess).
4.  AB and QP3.1 appear to display the same values for 
    any given !IDxxx.  However, they assign different names to many of 
    them.  For example: for !ID050, AB's name is 
    (Leisure-Gaming-LEISURE), while QP's is (Media-Radio/TV 
    MERADIO).  In fact, the names for more than half these symbols 
    disagree. 
Note, I have only recently even looked at sectors and 
    industries in AB.  This May have been happening for years without my 
    knowledge.  I have been using AB since at least version 4.2 and QP is 
    at least the fourth data base I have installed (it is the only one I am 
    presently using).
I tried to fix the problem with: File>Data Base 
    Settings>Flush cache -- Configure>Retrieve, without success. (I am 
    suspicious that there may be something wrong with broker.sectors and/or 
    broker.industries.)
Is there a safe, relatively easy way to fix 
    this?  By safe I mean that I do not want to loose any of my existing 
    Layouts.
Thanks for any help you can provide.
