CellDesigner ignores all rdf description block in case it contains not-supported bqmodel:isDerivedFrom
As bqmodel:isDerivedFrom is not supported by CellDesigner. In case I add to the block "rdf:Description" bqmodel:isDerivedFrom, CellDesigner ignores the whole annotations (even the ones that are handled) - so in CellDesigner it looks like there are non annotations even though they exist.
