aftermarket O2 Sensor causing MIL?

aftermarket O2 Sensor causing MIL?
Awhile back I had asked about using a aftermarket O2 Sensor and still receiving the MIL light stating the sensor was defective.
I recently aquired a Autel AL539B OBDII Diagnostic tool and can see live data which I can verify the O2 sensor is working, but for some reason after a couple drive cycles the MIL comes on and I get the DTC codes stating the O2 sensor voltage is to high basically p0138 and I believe p0135 DTC's
Do I need to return thses Bosch O2 sensors and get the Mopar/Dodge/Chrysler factory sensors ?
I know I had to do that with the 2005 T&C and even though what I am working on is a Durango it seems to me the same problem is arising something about the aftermarket sensors is sending incorrect info to cause the MIL to come on.
If I reset the MIL I can get a couple days and read the live data just find but eventually it will again set off the mil.

Oh Good I found the NTK ones and they are only $11 more for both of them, curious though NTK are listed as NGK is this normal?
what are the OEM ones as the NTK (ones I removed) have the exact same # but upstream is AF and Downstream is AG
where the NTK ones I found at Auto zone do not have the AF or AG at least not in their description I have not actually seen the unit in hand yet maybe it has those AF and AG #'s on them.
Only way I knew they were NTK is due to it being stamped on the ring above the nut part.
