The communication of OCF devices works differently, in this post I included some details:
Basically, the communication happens between the app and the device and this information is not required to go through the public API
So, that’s why the app can still see those values, I’ll ask the engineering team if there’s another option but I can’t make any promises.
Also, I’ll confirm if the attribute data won’t be used any more to request its removal from the capability.
