This should not be happening if you are using 1.18.2.2029 and you have DVR Settings for Enhanced Guide disabled.
Would like to see some logs and screenshots - may need to have a look at the db files if the logs do not identify the issue
So screenshot of the DVR Advanced Setting page confirming “Enhanced Guide” is off and Server logs after completing an NFL recording and matching to “NFL.”
