MSEL and nCONFIG behavior at power up

Hallo 

We used the Agilex5 device with Smart VID and AS configuration.

The device configured OK, but lately I notice the MSEL pins and nCONFIG pull down during VCCIO_SDM (1.8V), see attached figures,

Is it normal behavior? I don't see it on all boards

Thanks

Asaf
