Two options:
1) Upgrade to WLSE 2.0 from: http://www.cisco.com/cgi-bin/tablebuild.pl/wlan-sol-eng and this should fix the problem for good OR
2) If you still want to use 1.3, then the following workaround will let you push this Config Template.
a) in the Config Template->Finish, uncheck the 'Enable Version Checking' box and do not click on Validate button. Just hit Save to save the template.
b) In the Config Job->Finish, do not click on Validate, just hit the Save button to Save and run the job.
