TDC7200EVM:Time2 and onwards cannot be read correctly

Part Number: TDC7200EVM

Tool/software:

Hello
I am trying to do signal analysis using the TDC7200EVM.
Time1 can read the expected value, but the values ​​from Time2 onwards seem to be abnormal.
The yellow signal in the diagram is input to START, and the red signal is input to STOP.
The first pulse of the STOP signal is successfully detected, but the next pulse and beyond cannot be detected.
I thought that the first and second pulses that enter STOP after Start would enter Time1 and Time2, respectively, but is this wrong?
Or is it a hardware failure?
Please let me know.
