EXT_LFx pin of ADV7344

Question

Hello. 
 There are some questions about EXT_LFx pin of ADV7344. 
 The datasheet says that 12nF, 150nF capacitor and 170ohm resistor should be connected to EXT_LFx pin. 
 The issue occurs that mechanical shock by external makes some abnormal picture. 
 So, they tried to reduce the capacitor value(12nF->1.2nF, 150nF->15nF), then the issue is fixed. 
 Can ADV7344 accept above reduced capacitor value? 
 Best regards. 
 Kikka
