ISA Subelement Separator Not Being Recognized When Parsing Composite Element

I've been working on evaluating EdiFabric for a potential purchase of the professional or enterprise version and testing against a few sample 271 files obtained online; I'm testing with version 9.8.6. When parsing the following sample 271 file obtained from CMS using EdiFabric.Templates.Hipaa5010.TS271, the full contents of any non-null EB13 element (including the sub-element separator) end up in the first subelement (Loop_2110C_271.EB_SubscriberEligibilityorBenefitInformation.CompositeMedicalProcedureIdentifier_13.ProductorServiceIDQualifier_01).

So, even though the ISA below correctly specifies the vertical bar | as the subelement separator, the EB segment with HC|G0180 in EB13 is parsed to .ProductorServiceIDQualifier_01 = HC|G018 and .ProcedureCode_02 = null

I understand that delimiters specified in the ISA are supposed to be handled automatically according to other posts in the forums and based on a review of docs, so I suspect this may be a bug/regression. Given that I don't yet have much experience with the components I would welcome any guidance/suggestions as this is a pretty serious issue if it indeed proves to be a bug.  I'd normally root cause something like this myself, but I don't believe that source is available for the part of the system responsible for setting up subelement parsing.  Thanks in advance for any pointers/suggestions re: things to try.

Here is the sample 271:
