isolated margin detail level data missing

I am trying to access the isolated margin information such as different borrow limit with respect to different VIP levels. It comes to my notice that some of the information of the recent listed coins (namely: SKLUSDT / GRTUSDT / EGLDUSDT) has been missing from the websocket data.

Below is the websocket I use to access the data.

Below with the example of the extracted response.

-{‘assetName’: ‘GRT’, ‘levelDetails’: }, is missing.
