Object Repository isn't getting updated!

I am working on mobile automation and using Object Repository for UI Elements. Recently I tried updating a UI element in the object repository using “Edit Descriptor” directly from Ui Interaction activities like tap and get attribute as well as from Object Repository pan. It was observed that these methods to update object repository works with web automation activities but not with mobile automation activities.
If I edit a selector of Mobile UI Element its value, the changes won’t get reflected in the selector next time I use It. Either it is not saving the changes or resetting them. The same is not the case with selectors of web applications.
I am left with only one option as of now i.e. Override Selector Element option.

Is this a bug with UiPath ?
