Missing definitions for some CPC codes

[crew102]

Looks like patentsview is missing the definitions for some of the CPC codes. For example, the code of B32B is missing a definition in the CPC group bulk data file, but a definition exists for this group in the official xml scheme. I count 30 missing groups out of the 656 groups.

I don't see anything obvious in the xml or in the parsing code (relevant snippet shown below) that would indicate where the problem is coming from. Sorry.

I think the offending line is
https://github.com/CSSIP-AIR/PatentsView-DB/blob/30ae3cbc3e7a02c46ef64fd8fd2c2ac9bfceb250/Scripts/Raw_Data_Parsers/uspto_parsers/cpc_class_tables.py#L38

If I run locally with that line changed to
text_class = [t.text for t in text_need]

I get a title for B32B and none of the other groups are missing their titles. I don't know the intent of that line but the effect was that it erased titles that contained I.E. or E.G. Generated from CPCSchemeXML201802.zip: cpc_group.tsv.zip
