TFmini Plus Range Finder no data in short pulse

I seems to have data missing in short pulse from the range finder as attached:

From my understanding, the stat meaning is as below:

enum class Status {
NotConnected = 0,
NoData,
OutOfRangeLow,
OutOfRangeHigh,
Good
};

So my RFND is changing from OutOfRangeHigh->NoData and Good->NoData in short pulse consitantly, can anyone help to provide some advice on how can i solve this issue, thanks in advance!!!
