System retains old value even after changing it

Hi,

I was trying to change the properties of one of my EC in SDK using standard UI COD_APPOINTMENT Thing Inspector view by selecting the Undefined anchor and then clicking on Adjust Properties. Here for each facets 2 properties can be set Visible and Enabled. First i change the Enabled to True for one of the EC and then try to change it back by changing the dropdown value to False and apply, then Save & Activate, but it retains the same old True value.

Also i tried changing the value for Column Visible to False it did save first time but when i again went there to change it back to None it's not saving this new value.

Am i missing any steps or logic here or is it a bug. Why these properties value are not persistent. Appreciate any help ?

Thanks,
