ProxyPass iRule failing reading content on data group

The ProxyPass ver 10.9 has issues on retrieving the information stored on the data groups I got this error when trying to load the iRule (in the GUI the iRule loads but when I try the command tmsh load sys config not):

Code[root@asmjs2:Active:Standalone] config  zmore /var/log/ltm* | grep missing

The line 75 has this command:
