A complete trigger replacement and I bet your problem goes away. If you or a friend has a spare change it out and test.
Otherwise troubleshooting your unit may be cheaper than buying another trigger.
Check to see that the disconnector spring is installed large end down. If not correct and test.
Second if spring was correctly installed, replace disconnector with another of known value and test.
Last option is complete replacement of whole trigger unit.
I agree with what ROST said above.
