Classification attribute changes are not inherited

Case:
Two classifications: PARENT and CHILD
Table ATTR defined on PARENT ant incherited to CHILD.

Change to ATTR is required, but after ATTR modification on PARENT changes (DOMAINID, TABLEATTRIBUTE, LOOKUPNAME) are not reflected to CHILD.

Workaround:
Changing data from DB level.

SELECT
CLASSSTRUCTUREID, ASSETATTRID, DOMAINID, TABLEATTRIBUTE, LOOKUPNAME, INHERITEDFROM
FROM maximo.CLASSSPEC
WHERE
CLASSSTRUCTUREID LIKE 'LOC.MEET-ROOM%'
ORDER BY ASSETATTRID
