nRF Sniffer wireshark bad interval connection

Question

Hi all, 
 I'm using nRF Sniffer (2.0.0-1.beta), i didn't have any problem for follow connection between master and slave but now, I have a problem with time displayed in wireshark.
My interval connection max is 20ms (central). 
 I can find in connect_req link layer data Interval 16 (20ms) => OK 
 After Wireshark shows that : 
 REF Master	Slave	LE LL	26	Empty PDU 
 0.000360	Slave	Master	LE LL	26	Empty PDU 
 0.000616	Master	Slave	LE LL	26	Empty PDU 
 0.000946	Slave	Master	LE LL	26	Empty PDU 
 0.001291	Master	Slave	LE LL	26	Empty PDU 
 0.001633	Slave	Master	LE LL	26	Empty PDU 
 0.102369	Master	Slave	LE LL	26	Empty PDU 
 0.102698	Slave	Master	LE LL	26	Empty PDU 
 etc.... 
 Can someone explain to me what's wrong ? 
 Thanks in advance 
 Best regards, 
 MPS

ok, since multiple roles are in the central I think the connection events are being skipped so that it can scan for other devices and occassionally the scanner need to use the radio. This is confirmed by the fact that there is no packet loss (as the SN, NESN are in sync). I think the sniffer is capturing exactly as it happens. 
 Edit: The event counter is used to see the time line, so even if a event occured and a tx did not happen on the master side, the counter has to be incremented. This is generated by the sniffer and is not on the air.
