TEA19162 SNSMAINS noise issue

We observe circuit noise coupling into the SNSMAINS input of the TEA19162 controller, and causing weird issues with the gate drive. What is standard method to "clean up" the noise on this pin?

You can refer to AN11801 page116-'13.6 TEA19162: placing of SNSMAINS mains sensing resistors' for more information about filter noise.
