Sensor Dynamic discovery don't adds readed snmp limits

Help
1

Hi,
Found possible bug on Dynamic Discovery
Or I not fully understand the logic behind sensor limits.

it seems that snmp sensor limits are not written into database.
instead the calculated values are going into db.

I the example from the sensor sfpDiagRxPower below, the “sensor_limit” got from snmp should be -3 (warn_limit) or -5 (high_limit)
But instead a calculated value of -17.8505 is going int Database.
