Problems Enabling/Disabling Addons in Profiles

I am using Kodi V17 on an Android Lollipop tablet.

I am trying to use Profiles to create a different set of available Addons in a Kids Profile so I now have Master Profile and Kids Profile

All my Addons are available for Master Profile.
I have setup Kids Profile with Media Info and Source Info both set to Separate ( rather than Shared )
I am now trying to selectively Enable some of the Video Addons in Kids Profile by going into Kids then Addons\MyAddons and selecting Video add-ons from the list.
There, I see a list of all the Addons with “x” ( Disabled )
I can click Enable for one of the Addons and it works but when I try to Enable other Addons nothing happens.
I seem to have to exit from Kodi and enter again to do the next one and so one for all the other Addons.
Is this normal or a bug in V17 ?
