Missing Role Grants after datapump

Question

Hello OTN-Community,
I have a problem with datapump. I am using some include filters to get the relevant data exported. One of these filters inlcudes the ROLES of my database which starts with a certain expression.
After the export into another database these roles exists but all of the role grants and the grants to other users misses. The object grants are exported correctly.
What am I doing wrong?
The export script:
declare
/*some declare specification are not copyed*/
cursor curSchema is
select
distinct
t.Mdbn_Name Name
from
ProphetMaster.Dat_MdBn t
where
Upper(t.MDBN_Name) not in ('****', '***');
begin
-- Schemas festlegen
SchemaList := '''****'',''***''';
if ExportAllProphetUsers then
for recSchema in  curSchema loop
      SchemaList := SchemaList||','''||recSchema.Name||''''; 
end loop;
end if;
-- Dateigröße
FileSizeStr := to_char(MaxFileSize)||'M';
-- Verzeichnis
DirectoryName := 'PHT_PUMP_DIR';
execute immediate  'create or replace directory "'||DirectoryName||'" as '''|| PumpDir||''''; 
-- JobName
JobName := 'PHT_EXPORT'||DateStr;
-- Filename
if not FilenameWithDateTime then
DateStr :='';
end if;
Filename := 'PHTDB'||DateStr||'_%U.DMP';
Logfilename := JobName||'.LOG';
