I came across the same thing when I was testing a couple of days ago. I’ve fixed it in the version I then uploaded to GitHub. I’m not sure how this bug crept in, but the fault is in line 2299 of parser.t, which should read:
cmd.action.(role.objProp) = cmd.(role.objListProp)[1].obj;
You may want to make a temporary patch. I’m planning to release an update to adv3Lite in the next week or so, which will include this fix.
