Parse-error with 'CLASS' definition in 'SPECIAL-NAMES' paragraph (AcuCobol)

We are trying to parse Cobol sources.

Having a ‘CLASS’ definition in the ‘SPECIAL-NAMES’ paragraph causes the parser to fail, while the compiler has no problems with it.
Adding a ‘.’ at the end of the CLASS definition fixes the parsing error, but that does not compile!

Versions used:
Cobol: AcuCobol version 10.2.1, fixed format
SonarQube: Enterprise Edition Version 9.6.1 (build 59531)
