Configuration file uploaded by USB wont update Quick Texts on 66i but updates Contacts and Presets

Have been trying to update  the presets, quick texts and contacts on 66i using configuration file uploaded by USB cable . It works perfectly for the contacts and pesets updating them everytime as expected but always ignores the Quick texts. I have inspected the configuration file and the quick text updates are there in the file but they are ignored by the 66i during the restart/update process. Am on firmware 7.20. Is this a bug or am I doing something wrong
