Bugs about automatically creating Android kits and Android kits management

We will use "ACK" for an abbreviation for "Automatically create kits for Android tool chains" in the Android options tab(Tools->Options and select Android),and "AD" for an abbreviation of "Auto-detectiona" node in the "Kits" tab under the Build&Run tab,and "MN" for the "Manual" node in the "Kits" tab.

Every time we check ACK and press OK(not just Apply!),there will be one set of Android kits created under AD,and if we unckeck ACK and OK,the just created Android kits will be moved from AD to MN.If we repeat this ,there will be many sets of kits created.

And,every time we uncheck ACK and press Apply(not OK!), and then check ACK and Apply(not OK!),and do not OK and goto directlly to the "Kits" tab,there will be one more set of Android kits created under AD,and at this time if we select one of the kits(just created) under AD and press "Remove",QT Creator will crash...

Can you fix the UI not responding for 10~20 seconds(when get into the Android options tab or Apply or OK) bugs first so we can report more bugs with ease?Thanks!
