SRK2000A: IC skips the gate pulses.

Hi, 
We are working on LLC converter Vout=12V; Pout=100W.
We are using SRK2000A IC at the output.
We are facing some issues related to it.
The IC behaves as expected while driving the load from 30% to 100%.
But when we start reducing the load below 30% the IC starts skipping the gate pulses.
Primary side we dont see burst mode operation.
Attaching the waveforms for reference:
1. Full Load VGS and VDS waveforms; working as expected.

2. <30% load VGS and VDS waveforms; having issue.
